Can I upgrade Snow Leopard to Lion from a backup system?

Hi,
This is a bit of a roundabout question so let me establish what's going on:
-I just got a new Mac Pro 6-core a few days ago, which arrived with Lion installed.
-I backed up the fresh Lion system to an external drive and downgraded to Snow Leopard to retain compatibility with certain apps.
-I imaginge somewhere down the line I will have to follow suit and upgrade to Lion/Mountain Lion, so....
Is there ANY way I could use my backup of the fresh Lion system to upgrade my Snow Leopard (if need be) to prevent me having to purchase Lion to upgrade Snow Leopard instead?
Thanks for your help!
Andrew

Aside from the fact that it will probably not work, the point is that your license for the preinstalled Lion is only good for one machine. If you want it on any other machine, you will need to buy it. Why don't you just wait until you want to install Mountain Lion - if the terms are the same as they were for Lion, it'll cost you $20 to update all your machines.

How can I upgrade to Snow Leopard or Lion from Leopard 10.5.8?

I can't find any way to get Snow Leopard from the apple store. It is on Amazon for $100+ and there are lots of fake ''free'' downloads online, but I don't want to use them?
Is there any ways to get to Snow Leopard or Lion from this old opperating system?!
My mac is a 2008 Macbook Pro.
Thank you!

Hi,
I just bought the iphone 5 but have a 2009 Macbook Pro so was running 10.5.8. Needed to upragde to snow leopard then to mountain lion. S.L. is no longer available in stores. The guy in the shop told to cal apple support (0800 048 0408) but was skepitcal. Amazin was quite expensive so I ended up ringing just to check... TOTALLY WORTH IT! Got it for £13, when I would have paid about £70. Apparently they are trying to encourage people to get SL so they can get the icloud.
Ring up! Honestly, their customer serivce was so helpful and lovely. Whole episode has reminded me why I love Apple.

John Hammer said it best -- backup first and always. That's why Time Machine and periodic clones of your boot drive to an external disk are so valuable.
That said – the Lion upgrade will retain all user data, files, settings, mail, and preferences. Mind you that a few settings and their location have changed.
Before you actually use Lion, may I recommend spending the first evening looking at every single preference panel in System Preferences. Many of the user interface choices can be reverted back to mimic Snow Leopard if you choose.
Relax and enjoy Lion – it is amazing. Please holler if we can help further.

How do I upgrade Snow Leopard to Lion? I have installed OS X 10.6.8 Update Combo v1.1
I have another machine that already has Lion on it and I want them both to have the same OS version.

Not the iTunes App Store, but under the Apple
icon at top left>Appstore, likely only 10.8/Mountain Lion will be found, if you don't want that & want Lion, you have to call Apple & get a key for Lion download.
Call Apple Sales...in the US: 1-800-MY-APPLE. Or Support... 1-800-275-2273

Do make a copy of the Installer before running it, like baltwo points out.

Can not Upgrade Snow Leopard to Mountain Lion due to Bootcamp

This is a long standing problem I had since I bought my Macbook Pro (a purchase now I deeply regret) almost two years ago.
I keep asking around every few months, to see if anyone came up with a good solution. I hope someone can help me this time
When I decided to buy my Macbook pro 10.6.8 with Snow Leopard, Apple said that the macbook would run smootly both in OSX and Windows due to bootcamp dual boot. I was quite happy about that,since my job requires me to use some Windows-only software and I was curious about apple products.
Unfortunately, they fail to mention (or maybe they did not foresee) that upgrading anything on both OSX or Windows would have been a true nightmare. Right off the bat I spent countless hours trying to upgrade my graphic card drivers in Windows. More problems arrived every time a new software/upgrade/driver/OS update was coming up. The final blow was the release of OSX Lion.
With a Bootcamp partition it is not possible to upgrade the OS from Snow Leopard to Lion or Mountain Lion. The reason is because a recovery system can't be created. The only solution I found so far would be:
1) Buy two separate external HD
2) Backup individually OSX and Windows data
3) Re-install OS leopard
4) Upgrade to Mountain Lion
5) Creat a bootcamp partition
6) re-install Windows
7) re-install one by one any software on both OS (Matlab, Ansys, Office .... etc ... etc ... etc... [6-8 hours])
8) Restore all data
9) Wait for next OS release, DO IT AGAIN
Forgive me , but this is absurd. I simply refuse of waste so much time and money
Did anyone have the same problem and found a more cleaver way to solve it?
Thanks!!!!

This was solved some time ago. See the following:
I saw a reference to an Apple bulletin on how to solve the problem if Lion rejects your install AND you have a BootCamp partition.
It seems the issue is that the space at the "bottom" of your available space when Lion installs it's partition is already occupied by BootCamp. The fix was to go into Disk Utility; Select your Hard Drive; Select Partition; Move the bottom of your main partition "up" a bit to create a space for Lion; close Disk Utility; Install Lion; once Lion is successfully installed, go back into Disk Partition and drag the bottom of your main partition back "down" to the bottom of the window.
You need to create a space about 2 GB in size.

Upgrade Snow Leopard to Lion in Canada

Hi There! I would like to upgrade from Snow Leopard to Lion. My iMac is too old to go to Mountain Lion or Mavericks, but although it's obviously obsolete, I would like to have my computer running the latest software it can... I found a link that took me to a place in the US Apple Store to download a code to get Lion, but it didn't like my Canadian address. Is there a way to get to do this from Canada? Thanks!!
Branden

Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

Can I install Snow Leopard over Lion to install old software after hard drive crashed?

My hard drive crashed and I lost everything. I have a new hard drive, but when the repair shop installed my operating system, they installed Lion and I no longer have my prior updates. My computer had been updated a few times. I have a lot of software that only can be installed up to 10.7 such as Adobe Photoshop Elements 10, Office Mac 2011, etc. I was wondering if I installed Snow Leopard over Lion, would I lose Lion? Should I install Snow Leopard and then Lion again? I don't want to damage my like new computer and I don't want to have to go out and buy all new software. Is there a solution? Thanks in advance!

Sounds complicated! If I repartition the drive and install Snow Leopard onto the blank volume, will Lion still be there? Or, will the computer basically have two operating systems that I have to go back and forth from. Is this something a novice like myself can do?

How can I virtualize snow leopard in Lion?

I heard there is a way to run snow leopard alongside lion so i can run my powerpc applications

The makers of virtualization software do not support Snow Leopard, only Snow Leopard Server.
But it is possible to bypass this and force an installation of Snow Leopard into a virtual machine on a Lion Mac. I have heard of people who have done this with VirtualBox. It's not the easiest thing to do, but it can be done. You'll have to Google for the methods.
Just make sure you follow all the licensing terms - only install one copy of Snow Leopard in the VM, make sure you have no other copies of Snow Leopard running simultaneously under the same machine, and make sure you have valid licenses for both Snow Leopard and Lion.
Don't worry about the numerous claims that you will undoubtedly hear that "Snow Leopard is not licensed to be run under virtualization under Lion." They are myths.

Upgraded Snow Leopard to Lion, iTunes downgraded to 10.3.1.

I installed Lion today over Snow Leopard, and now when I try to start up iTunes I get this error message:
The file “iTunes Library.itl” cannot be read because it was created by a newer version of iTunes. Would you like to download iTunes now?
I click on Download iTunes, and Software Update starts up and tells me that all the software is up to date.
iTunes in the Applications folder is at version 10.3.1. Before the upgrade to Lion it was 10.5.3.
Time Machine can't restore the newer version of iTunes because "“iTunes” can’t be modified or deleted because it’s required by Mac OS X."

The current version of iTunes is 10.6.3, not 10.5.3.
You can download it from Apple's web site: http://support.apple.com/kb/DL1426
The latest version of Lion is 10.7.4.
Update your information, you list 10.6.2 as your current OSX version.

ADVANTAGES FOR UPGRADING SNOW LEOPARD MOUNTAIN LION

I have a late 2010 Mac book Pro 13" 2.26 GHz 4 GB and I upgraded to Lion when it came out but I reverted back to Snow Leopard, my main use for my Mac is music I'm using Native Instruments Traktor Pro 2 software with the Traktor S4 controller hardware to continue upgrading my Traktor software I need upgrade to Mountain Lion, the Traktor software upgrades are not critical right now. Will there be problems skipping the Lion upgrade, I'm debating if there's any value to upgrade when everything is working fine. There seems to be a divided consensus for the Mountain Lion upgrade.

A simple suggestion, get yourself an external Firewire
HD (USB will be to slow), clone your current SL installation
to it, spend the $19.99 and install on that drive. Use it
for a while and if you are happy, clone the install back to
the internal drive. If not happy, wipe the external drive
and you have an additional backup or data drive (can never
have too many backups).

Not if you upgrade alone, if you wipe and install/upgrade then yes.

Can I upgrade to os x lion from os x server

I've got a Mac Mini Server, and I'd really like to convert to the standard version of Lion when it gets released. Will I be able to upgrade directly, or will I need to reformat, install Snow Leopard, and then upgrade to Lion?

I upgraded from a snow leopard server on mac-mini to lion server from AppStore and now it does not work anymore. MySQL has disappeared, disappeared the configurations of my mail virtual servers the
Macports is gone, the web server no longer work.
my advice is do not update.

Upgrade snow leopard to lion please

Someone PLEASE HELP!!!
Just bought a used macbook. Just gone to upgrade to Mountain lion and it seems my machine wont run it despite being on Snow Leopard 10.6.8.
I need Icloud and facetime so the best I can do is upgrade to Lion 10.7.
But can I find how or where to do it?
Anyone??

Mountain Lion needs specific 64bit processors with NX capabilities, these are only found in Macs post 2008 and rarely before - .
Intel 64 alone does not help - in Lion this was enough : any Intel Core2Duo - . Also 2GB of memory are needed and even if Lion needs only 1GB I recommend to max out the Ram for either of the Lion's.
