Installation and Upgrade • Re: Zimbra 8.8.15 to Zimbra 10.1 Upgrade

1) Yes. Very likely won't work.

2) Yes you can do a direct upgrade from 8 to 10. The Install/upgrade script detects the current database and ldap schema and applies any required changes to bring it up to date.

I believe the "supported" route would be : upgrade 8 to 10 on 20.04, then upgrade Ubuntu to 22.04 then "upgrade" 10 to 10.

I've been doing some upgrade tests recently, and in theory you should be able to upgrade Ubuntu, then install 10 over the top and it'll work.

I've found when doing the OS upgrade sometimes it forces a removal of zimba-common-mbox-conf and that removes /opt/zimbra/conf/localconfig.xml.
My current OS upgrade script backs up localconfig, does the OS upgrade, restores localconfig then reboots into a zimbra upgrade.

Be aware when upgrading to 22.04 that Synacor still haven't patched zmfixperms, so the permissions for /var/log/zimbra.log will be wrong until the nightly logrotate.
My quick and very dirty hack for that is to : I don't intend to ever install on Ubuntu 10.04, so I just replace that detection with 22.04 to work around it until it gets sorted out.
