Upgrade from 5.0.8 to latest release

[snake007uk]

Hi,

I have Zimbra installed on my home server. I was planning on upgrading it to the latest release. Currently I have

Release 5.0.8_GA_2462.RHEL5_64_20080709164104 CentOS5_64 FOSS edition

It is working perfectly however I think its due an upgrade.

Are there any step by step guides to upgrading major releases?

Thanks

I second that request!

Running 5.0.5 GA Network Edition on RHEL 5.

I would recommend the following :-

1) Shutdown ZCS
2) Make sure all ZCS processes have indeed terminated
3) Take a good backup of /opt/zimbra
4) Upgrade to ZCS 5.0.19 first
5) Start ZCS and make sure all is okay
6) repeat steps 1-3
7) Upgrade to ZCS 6.0.2
8) Repeat step 5

What is involved in the upgrade itself? is it a script you run? do you have to install over the existing version etc...

Thanks

Just as when you first installed you download the correct version for your OS, extract the tarball, and as root run ./install.sh. The script will identify you already have ZCS installed and will perform a upgrade.

Great,

Ill do the upgrade this weekend. One last question, but simply backing up the /opt/zimbra folder, would this good enough for a restore/recovery?

[uxbod]

Yes, as long as ZCS was completely down when the backup was taken. To recover you would remove ZCS completely, install a dummy copy of the release you were using when the backup was taken. Removed /opt/zimbra completely and extract your backup.

Thank you for the prompt replies

I will report back my success/failure so that others in the same boat can benefit

OK, that doesn't sound that bad.

However, the part about upgrading to ZCS 5.0.19 I'm a bit unclear on.

I'm already on 5.0.5. I don't need to do the 5.0.19 do I?

Upgrade successful

Here is what I did for my upgrade:

1) Shutdown ZCS (/etc/init.d/zimbra stop)
2) Make sure all ZCS processes have indeed terminated (ps -ef | grep java) or (ps -ef | grep zimbra)
3) Take a good backup of /opt/zimbra (tar -zxvf myZimbraBackup.tgz /opt/zimbra)
4) Upgrade to ZCS 6.0.2 (run the install.sh script)
5) Start ZCS (/etc/init.d/zimbra start)
6) Verify everything is ok

I did not bother upgrading to 5.0.19. However When you upgrade to 6.0.2 it applies all the patches from 5.0.x
to 6.0.2 (see below)
