Upgrade from 8.6 to 8.8.15 Multi Server

Postby rbeach » Mon Apr 06, 2020 6:33 pm

Hello all,

We are planning a mail upgrade coming up and I have a quick question on the process.

We have a two server set up.

One Mail store server (LDAP is here)

All documentation that I see says upgrade the servers in this order:

Mailbox store

So my question is, do I only upgrade the LDAP on the first server (mailbox store) and then upgrade the MTA server. After completing the MTA server, I then go back and finish the rest of the install on the Mailbox store?

So my process would be this:

1. LDAP on mailstore server only
2. MTA
3. Mailbox store - finish remaining upgrades.

Thanks for any help,

Hi Rich,

Your mailbox/LDAP server should be upgraded in its entirety first, then upgrade the MTA server right afterwards.

Hope that helps,
