Hello all,

I have a client with the following setup currently running Zimbra 7.x

• Master LDAP + Proxy + MTA
• LDAP Replica + MTA + Proxy
• Mailstore + Logger Active Node
• Mailstore Standby


The above setup is running on 4 individual servers.

I need to replicate the same structure and migrate it to Zimbra 8.x with the least amount of down time and with maximum automation to avoid least human intervention.

Can any one on board, suggest me a plan-of-action to achieve my target ?

Thank you all for your time.
