[Users] 8.7.0 Upgrade Bugs

[L. Mark Stone]

FWIW we no longer upgrade mailbox servers; it's too risky as you saw and creates too much downtime for the users. 

Instead, we upgrade the LDAP, MTA and Proxy hosts to the new version of Zimbra, then we deploy new mailbox server(s) at that same newest version level, making one of them a logger host. We then move mailboxes from the old, un-upgraded mailbox server(s) to the newer mailbox server(s) and configure logging on all the remaining Zimbra servers to go to the new logger host (which has to be a mailbox server). A quick run of zmdedupe on the new mailbox server(s) after all the mailboxes are moved and then we run zmprov ds oldmailboxserver(s).domain.com. 

No end-user downtime, no elevated blood pressure. 

Life is good! 

Hope that helps, 
Mark

>> https://bugzilla.zimbra.com/show_bug.cgi?id=104451 <= One should maintain their
