Recommended tool for migrating IMAP servers

[Davide Marchi]

Hi Friends,
I would like to ask you a suggestion:
I need to migrate a imap server to a new one and then dismiss the old 
one.
Reading from relative Dovecot documentation page 
(https://wiki.dovecot.org/Migration), more tools are shown:

UW-IMAP's mailutil, imapsync, YippieMove and Larch.

The each mail servers are Linux based, one of this (mine) is Dovecot.
Based on your experience which of these tools would be preferable to 
use?


Thank you very much

Davide
