Hello Zimbra Team,
Can you please share your thoughts of how to best upgrade from RHEL7/ZCS9 to the latest setup of RHEL9/ZCS10.1 (once available)?
I doubt that ZCS9 will come to RHEL9, which for some strange reason, I had always planned. At the moment, I am looking at this approach:
(Based on https://zimbra.github.io/documentation/ ... Guide.html)
1. Upgrade Prod via inplace upgrade from 9.0 to 10.1
2. Install a new server running RHEL9 with ZCS 10.1
3. Sync LDAP via MMR from old to new serverr
4. Point Production Server to the new LDAP server
8. Redirect production connection to the New Server.
9. Migrate accounts.
10. Deprecate Production Server.
Ideally, I would like to have as clean systems as possible.
Another thought instead of going via MMR would be to rsync the zimbra folder (according to https://wiki.zimbra.com/wiki/How_to_mov ... her_server).
But that would probably keep lots of old junk files.
Thank you,
