Hi

i want to  upgrade Ubuntu 12.04 to 16.04.03 or 17.10.1. (Install fresh instalation 17.10.1)
I want to install fresh instalation and then copy emails to new e-mail server.

If you need to upgrade Ubuntu, here's one tutorial:
https://docs.iredmail.org/upgrade.ubunt … 16.04.html

If you need to migrate iRedMail to another server:
https://docs.iredmail.org/migrate.to.ne … erver.html

How about Iredmail PRO license ?
What's better Apache or Nginx ?
Perhaps there is some similar experience ?

thanks

Arnis
