Hi, I'm planing to upgrade my iRedmail host.

Instead of doing a distupgrade to Debian 7 i was thinking of migrating to a fresh new iRedmail server running ubuntu 12.04. Is there anything that i should be aware of when moving to a new server from debian 6 to ubuntu 12.04?
The main thing I want migrated is the email and users. Policyd, amavis etc I can fine tune manually.

So, this is what I can think of migrating to achieve the migration above:

1./var/vmail → newserver
Will the structure be ok? Debian 6 is running Dovecot 1.2 and ubuntu 12.04 Dovecot 2.

2.vmail DB → newserver
Dovecote 1.2 to 2 DB     Is there any diff in DB?

3.DKIM → newserver  + DKIM config adjustments
4.SSL-certs → newserver + config adjustments

Cluebringer etc I will do manually.
