Zimbra Upgrades

Overview

This is for an upgrade test

Take a backup of the main server
Do a restore to create a test server
Before starting the test server remove network card this will server two purposes, stop conflicts with the main servers MAC and allow a boot up to change the IP and hostname so you can test upgrade without taking the main server offline.
Do OS update from 10.04 to 12.04 then update zimbra to 8.0.8 or 8.0.9 then upgrade OS to 14.04 and then Zimbra to 8.6.0
Most of the below step are the same except maybe the firewall stuff

Remove Network card using proxmox interface
Start test server make some network changes these will have to be done via console as no NIC is present
Change the ip hostname and db.0.0.10 adjusting the serial # and the ips to 10.22.0.125 change ip to 125 as i have firewall setup for this ip and putty instance.
vi /etc/network/interfaces
vi /etc/hosts change ip
vi /etc/bind/db.computerking.ca

This is for an upgrade on the main server

Disable incoming email to the test machine for obvious reasons the below commands will disable incoming mail from efa-1 but still allow clients to connect to test server so they can access mails
ufw delete allow 25
ufw delete allow 325
ufw delete allow 465
ufw delete allow 587

Shutdown the server it will not be receiving email anyway
I like to shutdown all other backups servers so as not to overload the hypervisor
Take a backup of the main server

Check and regenerate certificates if needed

Before any updates do a database integrity check
