Upgrade from CentOS 5 to 7 and ZCS 7.2 to 8.6

Post by John.Robinson »

My client currently has CentOS 5 and ZCS 7.2 on a now rather elderly server. They've ordered a new server and I want to put a fresh install of CentOS 7 on it, and the latest ZCS.
From what I've read I'm assuming that I have to go ZCS 7.2 to 8.0 to 8.6. Now, as I understand it I can't upgrade to ZCS 8.0 on CentOS 5 then copy the installation across, nor can I install ZCS 7.2 on CentOS 7 and upgrade after moving across.
Can I just copy my ZCS 7.2 installation (/opt/zimbra plus the mail store I put on /srv/zimbra) to the new CentOS 7 machine, even if it can't actually start, then run the ZCS 8.0 installer and have it migrate everything? Or are there other intermediate steps I could take - without needing a CentOS 6 server - or should I use something else like the ZeXtras migration tool?

Use the ZeXtras Migration Tool - it's easy to use, does what it says on the tin and it's free and I've used it many times without problem. :)

Read the documentation, it is free to use for thirty days and I wouldn't recommend it if what I said was incorrect.
