Best way to migrate applications from Lion to Snow Leopard?

Hello! own a mid 2011 MacBook Pro and upgraded to Lion back when it came out. I've now realized that Lion and CIFS network drives don't get along well. I want to downgrade back to Snow Leopard. I didn't have any Time machine back ups or anything like that so I believe I have to do a fresh install, this shoudln't be a problem as I have a 6 TB FreeNAS box to back everything up to. My question is about software. Most of the software I have on my computer is free, but some of it, namely the Adobe Design Suite Standard, Quickbooks, and a few other photo/business related pieces of software have been purchased. Is there any easy way of reinstalling them? I guess what I'm asking is, how can I back up my software? Maybe a better question is how do I uninstall software in such a way so that when I reinstall it later it won't give me an error saying the serial number has already been used.

Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.
You will need to reinstall your third-party software.

Best way to upgrade MacBook from Tiger to Snow Leopard? I only have 1 GB RAM

I'm currently running the latest version of Tiger (10.4.11) on my Intel MacBook with 1 GB RAM, and I want to
upgrade to a later version of OS X. I understand that Mountain Lion requires 2 GB RAM, so I'm thinking that
I want to upgrade to Snow Leopard (10.6). What's the best way to go about this -- where do I get the upgrade, etc.,
and what do I need to watch out for in terms of compatibility with existing applications such as Microsoft Office?

Best way to migrate Applications across environments of different versions

Hello Gurus,
Source EPM Environment - EPM 11.1.1.3
Target EPM Environment - EPM 11.1.2.2
What is the best way to migrate applications for Planning , Essbase , HFM and also the related reports from 11.1.1.3 to 11.1.2.2 .
Any help will be highly appreciated..
Thanks
HyperEPM.

I tried with upgrading the application and it was done pretty smoothly as compared to the LCM import export method.
Now what would be the feasible way to move all the applications when following is the scenario and we need a minimum downtime.
1. Move from EPM 11.1.1.3 to EPM 11.1.2.2
2. DB used to configure EPM 11.1.2.2 should be fresh and not the existing one.
3. We want to move all the applications across to EPM 11.1.2.2 on the freshly configured EPM 11.1.2.2.
4. Move all the applications intact across the version.
Thanks

Best way to transfer application from Test Environment to Dev. Environment

Hi All,
We are try to create an application on Hosted Environment similar to www.apex.oracle.com.
We got two work space
1. app_production
2. app_test
My application will have 200+ tables and many other supporting object.
My question is in hosted environment what is the best way to copy application from test to production environment (P.S In hosted environment I can uses SQL Developer / TOAD or any other tool .. its similar to www.apex.oracle.com)
With my present workaround I have to use
Go to Utilites -> Generate DLL
and then export this and application..
The main problem is 200+ table and associated structures .. its very difficult to keep track ...
Can anyone suggest me any good way for HOSTED ENVIRONMENT

Hi,
Just an idea:
1 - Do a DDL export of the source env
2 - Do a DDL export of the target env
3 - Use some tool to compare those files and highlight the differences. There are even some tools that are smart enough to generate SQL statements to apply the differences in the target env.
I hope this helps.

How do I upgrade from Lion to Snow Leopard?

Snow Leopard has this great feature called Expose which is a great improvement on Lion's App Expose (and Mission Control).
Can someone point me to the steps I need to take to upgrade from Lion to Snow Leopard?

Written just for you (ok it's a paste)
Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
Disconnect other drives except the backup drive as to avoid any mistake.
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire disk of ALL DATA. (warning, everything will be gone and not recovered, OS, programs, files, Windows etc all gone.)
Note: You might want to hold c and boot off the 10.6 installer disk and use Disk Utility to format the new blank external drive instead of using OS X Lion that's hosed. Then reboot into Lion and copy files, be safer that way perhaps.
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP there, don't install OS X yet.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same drive name as before, and click Erase...
(note: if you want to "scrub" the drive of old files that haven't been overwritten yet, then use the Security Option > Zero Erase, takes a lot longer)
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
http://support.apple.com/kb/DL1399
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly recommended.
A lot of people use a Carbon Copy Clone of their boot drive to a new HFS+Journaled external drive (used only for this purpose) as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.

How can I downgrade from Lion to Snow Leopard?

Hello.
Yesterday, I upgraded my Mac to Mac OS X (10.7 Lion) from 10.6.8 Snow Leopard. However, I wish to downgrade.
Obviously, I would like to not lose any data at all. However, I have never downgraded before.
I still have the Snow Leopard installation disk that came with my Mac.
How should I do this? I was thinking it would be easiest to simply head on over to an Apple Store...
I did some research (aka Googling), and I read up on the subject quite a bit.
If I simply put in the disk, will I be able to downgrade from Lion to Snow Leopard as easily as the upgrade was?
Also, I have heard about holding down the "C" button to do this... how exactly?
I have never backed up my Mac, nor used Time Machine.
Also, is it possible to install Snow Leopard on a separate disk, and set it up so that I can switch between them on command?
Will all of my preferences be saved, or does this wipe everything, not just the system and libraries folders?
I realize that I have a lot of questions, and therefore I appreciate everyone's help in advance. Thanks again.
Sincerely, Zach

Backup your files.
Booting From An OS X Installer Disc
1. Insert Snow Leopard Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Erase Drive
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Upon completion quit DU and return to installer. Install Snow Leopard. Restore your files after the installation has completed.

Thanks for the information! My sister gave me the MBP for my daughter with Leopard installed. I purchased Snow Leopard and installed it, then my daughter purchased Lion. So I do have all the installers. If iWork wasn't included with any of those, I guess my sister purchased it while running Leopard. I'll have to contact her. Thanks again.

What is the best way to migrate zoning from an MDS9216i to a Nexus 5596?

I am migrating from a MDS9216i to a Nexus 5596. We have dual paths, so I can migrate one leg at a time and the full function for these switches is fiber channel attached storage.
What is the best way to migrate the zoning information? I have been told I can ISL the new and old switch together and then push the zoning to the new switch. Is that better than just cutting and pasting the zoning information to the new switch?
Also, I have to move four Brocade M4424 switches to the new switches - they are currently attached via interop mode 1, but will now be attached using NPIV. Has anyone done this before, and did you have any issues?
Any help or advice would be appreciated. Thanks!

Best way to re set-up iPhoto on Snow Leopard from Tiger

Currently have Tiger OS and iPhoto. My iPhoto Library is on an external HDD. Also I have separate folders on the external HDD containing some .jpegs which should be in iPhoto and all my movies .avi which could be in iPhoto. I am about to upgrade from Tiger to Snow Leopard.
What I am wondering is how I can consolidate my all my photos/movies into the new (Snow Leopard version) of iPhoto when I install. For example, in the iPhoto Library folder 2006, various .jpeg and .avi files from that year are not there - they are in a seperate folder "2006" (because I moved them using Finder when I was a Mac newbie).
Would it be better to copy all the .jpegs in the iPhoto Library into a single folder, then add all the stray photos from elsewhere in the filing system to that folder, then ask the new iPhoto to import photos from there? Or should I manually copy stray photos (eg. those from 2006) into the relevant iPhoto Library folder prior to the new installation.
Final note. I have around 50,000 photos and on my current system iPhoto is very slow to initially load up - is there a filing configuration which would make the app work more efficiently or does the SL version do that already?
Thanks.

Successful downgrade from Lion to Snow Leopard?

I will get to my question at the end, but first I must explain the situation:
I have an MBP Intel Core 2 Duo, circa 2006.
The case was falling apart so I bought a new MBP Intel Core i7, September 2011 model.
The new MBP came with Lion, which to my horror did not support PPC applications. I know some of the Mac OS hobbyists will say 'get over it'. However, I use Macs professionally and since I want to eat (so to speak), I must work, and to work efficiently I need Rosetta because there is quite simply no replacements available for some of my quirky software.
Lion has a couple of ways of stopping you upgrading back to Snow Leopard. Here is a simple way to do it, which allows you to keep Lion.
Boot lion and use the disk utility to create a new partition: I took 400 GB for the new SL partition and left Lion with 100 GB. Lion is pretty neat in allowing you to repartition on the fly.
Do the latest software update on the old computer (10.6.8). Restart new computer in target disk mode and connect to old computer using a firewire. On the old computer boot up Carbon Copy Cloner (freeware). Set the old computer as source and the SL partition as traget on the new computer. Simply accept all the default settings on CCC and let it to Clone (ie. backup) the source onto the target. CCC will generate an exact copy of the contents of the old computer's hard drive on the SL partition on the new machine. I believe it will aslo transfer FileVault protected accounts even if the user is not logged in.
Shut down new computer. Reboot holding down the optino key. For some reason the new SL partition was named IEF Drive (or something similar, I cant remember because it reverted back to its original name after a restart). The machine will boot into SL. Go to system preferences and select SL partion as your startup disk. All done in about 4 hours, most of which is waiting for CCC to finish! Whoopeeee.
So far it seems to me like EVERYTHING works just fine. I was particularly suprized that the Thunderbolt port was able to drive my external display either via vga or hdmi adaptors. I half expected that not to work because it is a brand new feature. Of course, it may not work with a Thunderbolt display. Howerer, since the machine is duel boot and I can go to Lion any time I feel like it.
I did have to reinstally Application Enhancer so that my Unsanity Haxies would work, but you have to do that after any migration.
Performance
Geekbench 32 bit overall score:   lion, 8473: SL, 8321
Novabench: lion, 882: SL 859
At first I had the impression that Lion was a bit swifter on start up and GUI response, so I used migration assistant to migrate my old computer user account onto the Lion partition. As expected all the login items and extra system services that came across from the old machine had a penalty for start up and shut down. After timing both I find that SL is slightly faster up and down than Lion. Even so, I am sorry not to be able to use Lion as I liked the look and feel of it right from the get go.
Never mind ...its function over form for me every time
Now my question is to ask whether others have exposed any weaknesses in a SL down/upgrade? It would help if you would post here so that I can head off any problems before I discover them in a critical situation.
Also, do the experts think SL will match the 64 bit performance of Lion, which I was unable to test because I am too mean to pay the 19 bucks for Geekbench?
Finally, I must say that after many years of daily use on countelss machines CCC has never once let me down, unlike TimeMachine.

I had said that the "function" of the user preferences in the ByHost folder won't be preserved on a different computer, not that the files wouldn't be there!
The ByHost folder contents are accurately preserved in a CCC clone, but the .plist files themselves are tagged with the "hardware UUID" of the particular computer they were made on, and will only function on that computer. Peek inside at the names of these preference files and you'll see. It's not an important issue in practice.
From Mike Bombich's CCC Knowledge Base, here:
Can I back up one computer and use the clone to restore another computer?
As long as the architectures match (e.g. intel vs. ppc), then the answer is **probably yes**. However, there are two caveats.
    Some of your preferences on Mac OS X are considered "host-specific." Preferences such as these will be ignored if you boot your cloned operating system and data from another machine. For example, the screen saver preferences are host-specific -- if you boot another machine from your bootable clone and the screen saver kicks in, you will notice that it has reverted to default settings. Do not fear that you have lost any data, your original preferences will be "restored" when you boot again from your original computer. To learn exactly what preferences are host-specific, navigate in the Finder to your home directory, then to Library/Preferences/ByHost.
    Don't install older versions of Mac OS than what comes with your computer. When you get a brand new Mac from Apple, it usually has a specific version of Mac OS X installed on it, and further, a specific "build" number. If you install an older version or build of the OS, for example by cloning your older Mac to it, then it may behave unexpectedly. When migrating your old Mac to your new Mac, be sure that your old Mac has been updated to at least one later release than what came on the new Mac. For example, if your new Mac came with 10.4.7, update your old Mac to 10.4.8 before migrating. If such an update is not available, use the Migration Assistant instead.

Problems using Migration Assistant from Tiger to Snow Leopard

I want to scavenge files and apps from a Power Mac G4 (PowerMac3,5) running Tiger 10.4.11 before I turn it out to pasture. Most of them were migrated years ago to another system and have been updated and upgraded over the years, but a few apps have no modern equivalent. Now I want to do one last "pull" to pick up anything left behind all those years ago, particularly apps for which the install discs are in deep storage at best and possibly discarded.
I'm trying to use Migration Assistant in a nearly virgin Snow Leopard 10.6.8 system (installed fresh from 10.6.3 retail optical disc, updated over the network, lightly tested). It has a single admin account, no other user accounts.
Possible complicating factors: the Snow Leopard system is Server running under Parallels 10.1.4 on Yosemite 10.10.2 on an Early 2008 Mac Pro (MacPro3,1) with third-party USB3 controller in a PCI slot.
At present, I'm using a portable drive with both FW and USB interfaces as an intermediate storage (FW on the G4 to clone the system drive, USB on the Mac Pro to connect it to the virtual machine). SL sees the drive just fine, can copy files from it, and can even run apps from it. Migration Assistant sees the drive and offers to migrate from it.
Two problems:
1. No matter what user(s) I select for migration, Migration Assistant tells me it is a duplicate account. Proposing an account name never used before does not help. As a result, no user files can be migrated. (Obviously, I could copy them in other ways, but I think MA should do a more thorough job.)
2. Migration Assistant offers to migrate absolutely no applications. Even applications that SL will run from the drive cannot be migrated. (Some are PPC apps, but SL will run them via Rosetta. Others are Universal apps.)
Am I expecting too much of Migration Assistant?
Is the Migration Assistant shipped with SL Server (and updated through Software Update) not capable of running under SL Server?
Should SL MA refuse to migrate any applications from a Power Mac, even Universal applications?
Am I missing something obvious?
Is there key information I have omitted?

Not sure what you meant by that statement. Although this "principle" may be more important to you than the twenty bucks, I know that my time is worth more to me than your twenty bucks!
What apps are you using?
markwmsn wrote:
I was able to install Snow Leopard (client) in a partition, and it was able to migrate users and many applications from the G4 clone on the portable drive. Some of the apps even run.
Then I went back to my SL Server virtual machine and tried to migrate FROM the SL client partition. Migration Assistant showed the same symptoms as importing from the clone directly (no apps offered, bogus "dup user" errors). I am forced to conclude that either (a) Migration Assistant 3.0.4/1.1 is broken when run on SL Server or (b) my new SL Server installation is broken. I'm either going to have to boot back and forth to run the old apps or find their installation media and reinstall them in my SL Server virtual machine.
Even worse, I realized that one of the antique programs I still haven't dug everything out of is a Classic application that had to be kludged to survive Y2K!
Thanks again, MIchaelLAX.
Anybody else have any clever ideas?
So, glad to see that Migration Assistant did work for you in Snow Leopard...

IMovie won't open after downgrading from Lion to Snow Leopard

Okay iMovie 08' and 11' both worked absoloutly fine on my MacBook Pro (17" Core 2 Duo 2009 model) when I had Snow Leopard installed.
I then upgraded to Lion and iMovie 11' still worked fine but Lion had a lot of bugs so I decided to wipe and install Snow Leopard again. I then used the Migration Assistant to move my Apps from a Time Machine backup to my Mac. Everything worked okay except Java was broken. Everytime I launched a Java application it would say Java 1.5 not found. I managed to fix this with a lot of Googling.
But now I've come across another issue. I noticed that iWeb, iPhoto and iMovie will not open. The icons bounce in the dock and then they finish bouncing and it appears to have loaded, the top menubar says the application name and I can click on File, Edit from the top menu and all the normal options are presented to me. But the main interface of these programs simply does not open. I managed to fix iPhoto by reading online about removing a folder called ProKit.Framework in my Library and that worked for iPhoto perfectly it now comes up and loads like normal. But iWeb and iMovie still do not load. I don't really care about iWeb but I do care about iMovie not working as I use that all the time.
Does anyone have any ideas on how I can fix this?
So far what I've tried:
1. Remove all traces of anything iLife releated on my Hard Disk including pkg receipts, cache files, .pref files and so on
2. Tried just reinstalling the entire iLife suite several times
3. Tried installing Quicktime 7 from the Snow Leopard Optional Installs DVD
4. Tried changing colour profiles on my Display (I read this worked for someone else, did nothing for me)
5. Made a new user account on my Mac and tried to run iMovie from that account, same result it 'runs' but the interface doesn't show up.
Thanks for any help you can provide

I just thought I'd reply to say that I just fixed this by deleting the following folder and afterwards running software update.
iLifeMediaBrowser in /Library/Application Support
It would appear that if you erase this folder and then reinstall iLife it does something that brings this folder back or recreates it. But if you run Software update after erasing it, it downloads this folder from Apple (about 2.5MB) and that fixes the problem completely.
Hope this helps someone else!

ICal and Mail don't work after downgrade from Lion to Snow Leopard

Hey everyone, after an extremely awful time with with Lion (it knocked out of my audio interface AND my wireless) I downgraded back to Snow Leopard yesterday. I made a Carbon Copy of my Lion drive with all my data on an external drive (which I still have) and after wiping my local drive clean I reinstalled Snow Leopard from my disk. After it was done I chose to transfer data from another system local system (I selected everything) and an hour and a half later everything was transferred over. After doing a software update, I've found that I get big error messages with iCal, Mail, and even the App Store that say they can't open and I'm assuming that it has to do with incompatible data that got transferred from Lion. Any ideas on how to get those programs back up and running?? Thanks so much for you help!

Furthermore you have to ensure that chipset driver was installed too.
The notebook supports ATI graphic chip and AMD chipset. The chipset driver is part of the ATI graphic card driver and therefore you should ensure that this driver would be installed too.

Kernel panic during downgrade attempt from Lion to Snow Leopard

Hi guys,
I am experiencing two issues with Lion so I decided to downgrade to Snow Leopard using my Time Machine backup.
So I rebooted, held the option key down, booted from recovery disk, selected the option to select a time machine backup. I picked the latest 10.6.8 save.
Then, I waited for recovery... After completion, I noticed that I could not access my System Preferences anymore in SL. So I realised that I should have done the first steps using the option from the SL disk instead of the recovery disk.
I restarted with the SL disk in, tried to boot from the disk and got a scary kernel panic every time I tried (right when it tried to boot from the SL disk). I do not know what to do, I simply want to go back to SL backup (from my time machine) before Lion upgrade.
But, my only option to boot up is with a Lion DVD...
Any help would be greatly welecomed!
Thanks!

Just wanted to let you all know that I figured out why I was getting the kernel panic error: I was using an old SL upgrade DVD (the very first that was available in Apple stores when SL came out) instead of the install DVD that came with my iMac.
I just tried to boot from the right DVD and it worked fine. This thread can be marked as resolved.
Thanks!
