[Dovecot] backing up maildir dovecot files

[David Mehler]

Hello,

I'm having to migrate servers. Both are dovecot2 systems. I'm wanting
to copy over my mail store from one system to the other. I'd like to
preserve dates/times of emails. These are maildir setups on both
boxes, I'd like to be as transparent to the end user as possible. I
currently have the first dovecot system offline and the second dovecot
system is offline.

Recommendations?

Thanks.
Dave.
