migrating dovecot to new server

[Francis Augusto Medeiros-Logeay]

I did what Aki said. Actually I moved it all to a new server and to docker containers. From Dovecot 2.2 to 2.3. And it worked fine. Of course one always forget something - the path for the certificates, the different directory for mounting storage, etc. 

But am surprise and happy that it worked very well.
