Can I updates mailbox servers at the same time, not one after the other?

Postby TLS » Tue Feb 13, 2018 9:18 am

I want to update multi-server Zimbra OS from 8.6 to 8.7. I know that updates order is:
- ldap
- mta
- proxy
- mailbox.
I had always updates Zimbra servers one after the other, but now i would like reduce time entire operation.
I have several mailbox servers. Can I updates mailbox servers at the same time, not one after the other?

Thanks for answer.

Multi-Server Environment Upgrade Steps

Upgrade the servers in the following order. Update each server one at a time, following the instructions under "process" below.


Is it really necessary? No one installed mailbox servers at the same time? What will happen if I install them simultaneously?

As long as the ldap servers are all updated (and you don't have mailbox servers running ldap) that's fine. It just means you're environment well all be offline at the same time is a.

I've upgraded multiple mailbox servers simultaneously with no issues as well -- provided that the mailbox servers have no other Zimbra services running on them (aside from a logger host); LDAP, MTA and proxy must be updated first.

Hope that helps,
Mark
