Learn how to migrate Zimbra to New server in an easy manner. You can also move Zimbra mailboxes from one computer to another computer also. A user can do it just by resyncing old ZCS mailboxes with the new ZCS server. I will explain here step-by-step how to do that in a simple way.

Why Need to Migrate Zimbra to Another Server ?

Hello friends! I would like to switch Zimbra from my old server to the new one (a situation that I find very common) but unfortunately, I cannot get official instructions on how to do it. My old server version is:

Version 5.0.12_EN_2789.RHEL5_64_20090126051426 CentOS5_64 Edition FOSS

My New Server is

Version 8.7.6_EN_1776.RHEL6_64_20170326144124 RHEL6_64 FOSS Edition.

I read a few docs, but unfortunately, they all expect the same Zimbra OS and version (very strange assumption: why would anyone want to migrate to and from the same version).

Can you provide a migration guide for different operating systems and versions of Zimbra? If there is no such recommended practice, you will be very grateful if you suggest it.
