SLESUpgrade
This procedure is based on SLES9 to SLES10. OpenSUSE 10 to OpenSUSE 10.2, Debian 3.2 to Debian 4, and FC4/5 to Fedora 7 should be approached similarly.
- ckconfig zimbra remove
- take full backup
- zmcontrol stop
- follow the operating system upgrade procedure
- follow the Zimbra upgrade procedure
Caveats
- Make sure /opt/zimbra/redolog/redo.log is owned by the zimbra user after step 3. Depending on what kernel version is in use, the system may hit a SUSE kernel bug. This impacts Debian 3.2 and SLES9.
- There are some chmod errors during upgrade process.
chown: missing operand after `root:root`
They happen immediately after module upgrade. These appear to be harmless.
