HT3607 How do I upgrade Mac OS X Server to OS X Lion

How do I upgrade to 10.6 or higher as the software I want to use needs 10.6 or higher.
I currently have Mac OS X Server 10.5.8.

You should be able to find it under "Featured".
Here's a good guide for you but I'd wait for Mountain Lion, coming soon.

Customers can still purchase Snow Leopard from Apple's online store's telesales agents.[1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775.]
Once you have upgraded to Snow Leopard you will need to download and install the Mac OS X 10.6.8 Update Combo v1.1. You can then access the App Store where you can purchase and download Mountain Lion.
Be sure your computer meets the minimum requirements:
Apple - OS X Mountain Lion - Read the technical specifications.

How to upgrade Mac OS X 10.5.8 to Lion

How can I upgrade MAC OS X 10.5.8 to the latest version of LION?

First you need 10.6.6 or higher...
Snow Leopard/10.6.x Requirements...
General requirements
   * Mac computer with an Intel processor
    * 1GB of memory (I say 2GB at least)
    * 5GB of available disk space (I say 30GB at least)
    * DVD drive for installation
    * Some features require a compatible Internet service provider; fees may apply.
    * Some features require Apple’s MobileMe service; fees and terms apply.

It looks like they still have it...
http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA
If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory[14]
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading[14]
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

Note the 867 Mhz or higher (1 Ghz is higher) is necessary for 10.5.
Note 10.5 also gets rid of Classic, the compatibility for Mac OS 9.
Note 10.6 to 10.6.8 can be upgraded to 10.7 or 10.8 as long as you have a Core2Duo minimum. 10.7 or later are not compatible with Rosetta, the Mac OS X tool that lets pre-2006 software run on newer machines. For more on each, see these tips on 10.4, 10.5, 10.6, 10.7, and 10.8.
If you meet the requirements after purchasing the 10.6 installer CD.
10.4.4 through 10.5.8 can be upgraded directly to 10.6.3 to 10.6.6 to 10.7 to 10.7.5
10.4.4 through 10.5.8 can be upgraded directly to 10.6.3 to 10.6.8 to 10.8 to 10.8.4
10.7 & 10.8 are separate purchases, and can be downloaded from the Mac App Store once you are at 10.6.6 or 10.6.8 minimum depending on where you are at.

HT2476 How do I upgrade from snow leopard 10.6.8 to lion 10.7?

I get an error message when tryin gto access the mac app store from my apple menu and any browser. I want to upgrade to iMovie '11 from '09. I also want to upgrade from snow leopard to lion.

Depends upon your machine if it can handle Lion or not.
Did you read the minimal specs? 2GB of RAM and a Intel Core 2 Duo (not Intel Core Duo) it really needs 4GB of RAM.
I don't advise any machine that came with 10.5 originally to upgrade to Lion, it's just too much for that older hardware and 10.8 is coming out very soon and that will not run on a lot of older machines so your behind again and having to buy all new software.
As you should know, your investment in PPC based software and hardware drivers for third party machines is not going to work in 10.7.
http://roaringapps.com/apps:table
Perhaps you might want to wait for a new 10.8 or 10.9 machine.
If your sure about Lion, I highly advise making a bootable clone on a blank external drive first, makes it a cinch to come back to Snow.
Or at least disconnect your TimeMachine drive so it stays on 10.6, then you can erase from the disk and restore from TM.

Upgrading Mac OS X Server 10.6 to Mac OS X Server 10.6 to fix issues

I have a new XServe that was migrated from a G5 10.5 Server. Mac OS X 10.6.2 appears to have caused some issues which I did not realize until I attempted the 10.6.3 upgrade which utterly failed. It appears that 10.6.2 is not running many cli tools and in 10.6.3 I have found the entire var dir at least is incorrect. Tools in 10.6.2 that are not working include locate, ln, and man if not more.
I would like to reinstall. This server is bound to a AD server and I have read that you can upgrade 10.6 server to 10.6 server so I wanted to verify this as it would be the simplest way for me to do this.

I made a clone of the server boot drive and ran some test to see what was possible. This can be easily done by erasing a drive and then installing a fresh Mac OS X Server 10.6. Upon reboot supply the serial number and then it will ask to migrate the data and you can choose the existing install (in my case I had one clone with 10.6.2 and one with 10.6.3). After this I tested to see that the OS was in good shape unlike the 10.6.2 which was missing key unix functionality (man, ln, and others). I then updated with the Combo updater to 10.6.3 v1.1 and all was well.

How does migrating/restoring Mac OS X Server compare to Mac OS X?

I’m thinking of reinstalling the system software on our server (we have a bunch of problems we can’t get rid of) and I was wondering what the process is like.
We have a Time Machine backup and I was wondering how similar the process is to reinstalling/migrating a client installation of Mac OS X?
For instance does it give you the option to only restore files and data (such as Wiki content), or are you forced to restore all settings, users and preferences as well?
I’d prefer to just restore files and data and then manually recreate users and settings, in the hope of ridding ourselves of some of the problems we have (such as iCal server constantly asking for passwords and an inability to add or remove users using Server Preferences).

It's more a case of looking at the logs and not really knowing what I'm doing. Suffice to say I've taken the trouble-shooting road to my limit.
Mainly we have issues with iCal Server which keeps asking users for their passwords:
http://discussions.apple.com/thread.jspa?messageID=5936657
And now we have this error 14120, since 10.5.6, that causes us not to be able to add or remove users in Server Preferences:
http://discussions.apple.com/thread.jspa?messageID=8773646
I assume by the advice I'm getting from both of you that the migration tool for Mac OS X Server doesn't include the ability to bring only data files over minus all the settings and users?
I'm happy to do a clean wipe. I just want to be sure I can pull across calendars and Wiki data reasonably easily if I do it manually, as I'm not an IT pro. I'm only a CAD Manager and all my knowledge with these things is only through day-to-day experience.

How can I upgrade from os X server 10.6.8 to the 10.8 server

I want to upgrade to the current version of x server from 10.6.8.
The available pathways to get there do not seem to exist.
How does one accomplish this?
Thanks...

For the upgrade approach, first determine if your current (presumably Xserve?) server supports OS X 10.8 (client), then (if so) purchase OS X 10.8 (client), then purchase and install Server.app. The OS X client upgrade will leave the server bits alone, and the Server.app server installation should detect the server bits and upgrade them.
One or more backups are strongly recommended.
The other approach is a new server, and migrating individual service settings and data manually. This is far more work.

How do I install Mac OS X-Server on my Intel Base-Dell XPS? What's I need to have for this installation?

I have Dell XPS with Quad core Intel CPU, 4 GB RAM and 500GB HDD + 500GB RAID. I really want to install Mac OS X Server on it but I can not find where to buy OS X Server and I'm not sure that it suitable to my XPS, I'm afraid that is not acceptable to install. Anyone have idea about this please give me some information,thank you.

Hello Benz_KU,
I am afraid you won't be able to install Mac OS X server on you Dell computer. There are technical reasons for that as well as legal reasons: according to the "Software License Agreement for Mac OS X Server":
"This License allows you to install and use one copy of the Mac OS X Server software (the “Mac OS X Server Software”) on a single Apple-labeled computer at a time."
Best regards

Why Waiting for App Store to download Mac OS X Server Add On. stopping Lion download?

I just purchased Mac os x lion and this message is popping up : Waiting for App Store to download Mac OS X Server Add On.
Help! How do i get it to install?

Ran into this myself on a new MacMini Server. I renamed the ServerVersion.plist file in /System/Library/CoreServices/. That allowed the install to start. Unfortunately it seems the installer is setup to install that at the same time. I renamed the file back before the restart and it complained on restart that the server install wasn't found.
So I thought I would try downloading it on another computer with Lion. That didn't work either. As soon as it finished download it installed and deleted the installer.
What a pain.
If you can start from scratch, you should be able to rename the file, do the Lion install then after the Lion install rename it back. Then do the server install. I'm not sure what that will do to existing server configs though. There must be some reason Apple set up the Lion installer this way.
Oh, now I can't reboot into my existing OS. It keeps rebooting into the installer. Tried the option key and both options are named something like base os. Neither boots my existing Snow Leopard. Gonna have to get an external DVD drive and install from scratch I think. Luckily this is a new server not in production, so not a big deal. I hope people with production machines read the boards and tread carefully.

HT3854 Not applicable in Mac OS X Server v10.8 (Mountain Lion)?

This chart seems not applicable in Mac OS X Server v10.8.4 (Mountain Lion) [Server v2.1.1].
I have 32GB of RAM but the maxproc limit is still 2500, no matter setting via launchctl (the new way), sysctl (the old way), ulimit (the soft way), or both of them.
Commands applied:
$ sudo launchctl limit maxproc 2501
$ sudo launchctl limit
          cpu         unlimited      unlimited
          filesize    unlimited      unlimited
          data        unlimited      unlimited
          stack       8388608        67104768
          core        0              unlimited
          rss         unlimited      unlimited
          memlock     unlimited      unlimited
          maxproc     2500           2500
          maxfiles    1048576        1048576
$ sudo sysctl -w kern.maxproc=2500
kern.maxproc: 2500 -> 2500
$ sudo sysctl -w kern.maxproc=2501
kern.maxproc: 2500
Files also created / modified accordingly:
/etc/launchd.conf
/etc/sysctl.conf
When I see the source code of the Darwin kernel (unix_startup.c), it works like it is specified here. But I still cannot I wonder whether the kernel calls srv_setup() and bsd_srv_setup() properly. I would like to find a way (via systemsetup command, modifying com.apple.Boot.plist, applying NVRAM parameter, etc.) so that bsd_srv_setup() would be called with a larger "scale" parameter. Or perhaps is there any way to compile a custom kernel from source and replace the system one?

Gil,
The command with one parameter (known as "both" in manpage) is the same as the one with two parameters (known as "soft" and "hard" respectively in manpage) - it will be treated like supplying two parameters using the same value:

How do I upgrade Mac OS X 10.4.2?

I would like to upgrade my system (10.4.2) to a higher version. How do I do this without having any of my applications (photoshop, flash, etc.) deleted or any of my files deleted?
Thank you!

I recommend the following procedure:
A. Repair hard drive and permissions.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.5.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X. Note that Disk Warrior will not work on Intel Macs.B. Clone your existing system to an external Firewire drive.
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the startup or source volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Drag the startup or source volume to the Source entry field.
5. Select the backup or destination volume from the leftside list and drag it to the Destination entry field.
6. Check the box to Erase Destination. Skip this step if you've already formatted the drive.
7. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked.
8. Double-check you got it right, then click on the Restore button.
C. Download the Combo Updater for the version to which you want to upgrade from http://www.apple.com/support/downloads/.
D. Boot into safe mode to install the Combo Updater. After the update restart normally.
