8.6 to 8.7 upgrade questions

Postby roger_m » Tue May 14, 2019 2:44 pm

Wanting to upgrade the latest 8.6 to 8.7.11

6 servers in the system. 2 LDAP, 1MTA+Proxy, 3 Mailstore.

During a prior upgrade to 7.x up to 8.5, we did a modified rolling upgrade.
AFter upgrading LDAP/MTA and Proxy to 8.5, we installed new 8.5 mailstores and then migrated the users from one mailstore to the new ones. When we did the 8.5 to 8.6, it was just an inplace upgrade.

I'm not too thrilled with the existing file system layout, some of the partitions are a little tight in space.
I'd like to do something similar from 8.6 to 8.7. Upgrade the 2 ldaps and the MTA/Proxy server, then create a couple of new mailstores, then migrate the users from the 8.6 to 8.7 stores.
Any problems with this scenario?

If I do an inplace upgrade instead, what sort of down time should I expect? Roughly 3000 users, with a few TB of space in use. I'm guessing the mysql schema change is probably just taking time due to the number of users, rather than the amount of mail space.

Hello roger_m,
take a look at the free Zextras migration tool to perform Zimbra upgrades, it simplifies a lot the upgrade procedure: https://wiki.zextras.com/wiki/Migrate_Zimbra

Rolling upgrade works from 8.6 to 8.7.
Also to 8.8.

There are bugs in some specific setup.
For example if you try to enable 2FA before the end of the upgrade: https://bugzilla.zimbra.com/show_bug.cgi?id=105056

I saw that about 2FA.

Anybody know how long this upgrade would take?
