Re: Upgrading Zimbra 8.0.5

If you don't want to see any DNS 'outage' then I'd suggest you add a DNS MX record at a lower priority for the new server, when you're ready for the changeover you can just remove your old MX record and mail should just arrive at the new server.

Re: Upgrading Zimbra 8.0.5

Ok, a new server is been deployed (Centos 7) so the upgrade is no more an option. I'll install the last zimbra Open Source.
