Zimbra collaboration edition 8.6.0 upgrade

Hi.
In a virtual machine with centos 7 I installed Zimbra 8.6.0 collaboration edition. Now I should update the version. I copied the virtual machine to test it first and figure out which procedure to follow.
The mail server goes to download the emails from the Aruba webmail and stores them and then redistributes them among the various local clients. I ask you if it is possible to block the download of the emails or go into the configuration of the accounts and temporarily change the configuration to not allow the server to download new emails.
The best thing is to do the version passages from 8.6 to 8.7 and successes or better to reinstall a new server and reconfigure everything then reloading the backups?
I have never done updates or migration procedures and I ask you if there are any guides to follow.
THANK YOU
Andrew

Hello,
I suppose that Zimbra server downloads email from Aruba webmail using POP3 or IMAP protocol, so I'd suggest you to stop Zimbra services or to temporarily block POP3/IMAP ports using iptables, e.g.
Code: Select all
sudo iptables -A OUTPUT -p tcp --dport 110 -j REJECT
. Do this for all possible ports (143, 993, 110, 995).
A common suggestion on this forum (that I endorse) is not to perform an upgrade of Zimbra on the same server, but to create a new server, install the latest version of Zimbra (now 8.8.12 is available) and then migrate emails using Zextras migration tool:

Thanks @7224jobe
I'll study the migration tool I've seen for 30 days it's free and I can test it.
It really seems like the optimal solution for my work.
Thanks a lot.

Yes, install dnsmasq on the server to bypass the MX record check, follow this Zimbra blog post:

Hi
Installing DNSmasq is not mandatory to bypass MX check.
Just answer the installer question or leave blank.

You haven't entered the domain name, you have put the FQDN of the server. You should enter the domain name only i'e':
