[Users] OT: xfer emails from imap server to another one

[sylpheed at 911networks.com]

Not exactly a CM question, but people have a lot more experience with
IMAP than I do.

We are moving providers/mail server. The domain name stays the same.

3 Users: 

* User 1 (me) I use CM. Moving is simple for me, all my emails are
  stored locally and just have to change my CM settings.
* User 2 and 3: they use webmail/roundcube and point the imap server.

How can I transfer their emails from imap server 1 to imap server 2
by going locally? 

The domain name is currently pointing to IP1 and will be changed to
point to IP2.

Thank you
