Successfully Upgraded 6.0.2 to 6.0.3 on Centos 5.3 64bit

I've successfully upgraded one on my Zimbra server from 6.0.2 to 6.0.3 running on Centos 5.4 64bit. It was a smooth upgrade..just few minutes.

I'll upgrade my other 3 servers very soon..

Thanks to Zimbra! Good work guys.

There is no issue so far, all servers are running fine!

We've upgraded testing server too. Soon we'll go into production. also Centos x86_64.

Advice for backup:
1. stop zimbra
1a. check if every process is really stopped. don't want to see stalled mysql or something - happened to me once
2. tar zimbra installation folder
3. tar /var/lib/rpm !!! (I forget often to do this)
4. START ZIMBRA!!! (else upgrade could fail)
5. upgrade
6. if everything works, delete backups, else untar and try again
