OS Update/Upgrade...?

[NoDoze]

If I shutdown zimbra, update/upgrade the OS, then start zimbra...will I have any issues?

Is it recommended to keep the OS updated/upgraded?
Or is it only recommended to update/upgrade the OS when zimbra is updated?

Of course all the necessary backups will be made prior...

Thanks!

Please update your profile with the following information so we can see which version of ZCS and OS you are running

su - zimbra
zmcontrol -v

That's really a difficult question to answer. I've done it before with no problems, but the chance of having an issue definitely exists, and you have to be prepared with a good backup of your system. I did an Ubuntu upgrade from 6.06 to 8.04 without any issues, but doesn't mean it would go smooth for everybody. I could be running on different hardware and using different drivers from the next guy. So many variables involved to give you a straight answer that it will work with no issues. When I upgraded I did the Zimbra shutdown and then did my OS Upgrade, reboot, and Zimbra started with no issues. I've since done a total rebuild and converted from 32bit to 64bit, but that's a whole different story.

Hmmm....updated my profile with zimbra version....

I'm running Cent OS 5.0...thinking of upgrading to 5.3...

So we're not talking a HUGE update/upgrade, just an incremental update.
What I worry about is the kernel update.....cause I know some packages need to be recompiled to function with a newer kernel, was wondering if zimbra needed recompiling or something like it?

But from the sounds of it, it shouldn't affect it....?

Thanks!

Hello!

Been asking myself how to do this as well.

I've got a production env. with Zimbra 5.0.10 on SLES 10 - 64bit. What i'd like to do is upgrade the core OS to SLES 11 64bit and then Zimbra to 6.0.2.

For this, i've set up a test env. with the copy of the production server. It's on a separate network with different Zimbra hostname etc.

After upgrading SLES 10 to SLES 11 Zimbra (the 5.0.10 version) stopped working. I thought of this to be expected, since the install was made on SLES 10. So i downloaded the 6.0.2 for SLES 11 and tried to upgrade.

That's the Error i get when running the upgrade:

Do you want to verify message store database integrity? [Y] 
Verifying integrity of message store databases.  This may take a while.

Killing mysqld with pid 18996  done.

After that, the installer just quits to prompt.

If anyone has any ideas on how to approach the upgrade i'd be very grateful .

David,

The ZCS 5 rpms you have on your system are for SLES10, the ZCS6 rpms you want to install are for SLES11, and you already upgraded your OS to SLES11, right?

If so, you are I believe in a very, very bad place, unfortunately. In our experience, the ZCS installer essentially presumes/requires a working ZCS installation to do an in-place upgrade, but you now have ZCS SLES10 rpms on a SLES11 system (different kernels, gcc compiler versions, etc.) so you are essentially stuck.

It's nice that Novell SUSE support in-place upgrades of their OS, but since there are no SLES11 ZCS5 rpms, you can't take advantage of that.

IOW, you need a second server to do this upgrade:

1. Install SLES11 on new server.
2. Upgrade ZCS5 to ZCS6 on old SLES10 server.
3. Install same version of ZCS6 on SLES11 server.
4. Perform restore/server move procedure to migrate ZCS6 data from old SLES10 server to new SLES11 server.

If you have indeed already upgraded your SLES10 box, unless someone else has a more clever idea I think you are going to need to blow the OS away, reinstall SLES10, reinstall Zimbra and then do a restore before you can start building your new (separate) SLES11 box.

I know that's not what you want to hear, but as we are a SLES shop I think that's about where things stand.

All the best,
Mark

I was about to ask the same question.
I thought the right way to do this is upgrade CentOS and then upgrade Zimbra.

If you're talking about CentOS 5.4 then that's a point upgrae not a major upgrade to a new release, you should have no problem upgrading to CentOS 5.4 with the usual proviso of taking backups first.
