I have two concerns:

That is a postfix issue/area.

Right. If it's time-critical, people often reduce the TTLs to 60 seconds before a move, then readjust afterwards.
What I do usually is to rsync the home contents (I already have duplicated the users accounts and passwords), the /var/spool content and change the dns zone to reflect the new server.
Yep, sounds good.
but, being imap, I wonder if I couldn't have both servers running with the same mail content (of course with different domain names)?
You mean with two copies of the same mail or with one shared copy?
of course I can add an alias on the present server to copy mail to the new one. What can I do best?
I would prepare the new server as required and reduce the TTL for your MX to 60, maybe also for the IMAP server. Then stop both, copy the content across, then start both on your new server. Then update DNS. I've done that a couple of times with no issues.
If DNS is a problem, you could just move the IP-addresses.
