I migrated to my new server by drag/drop from Thunderbird. Using IMAP. 
Using Thunderbird 2.0.0.24. No command line needed to convert from 
server to server, all done via the GUI of the client.

Original server was mbox, destination is dovecot with maildirs.

The ONLY problem I had was with folders which contained a "dot" in the 
name. An old folder called "2010-june.providers" was understood as a 
folder called "providers" inside a folder called "2010-june" due to the 
name convention used in the dovecot server. The copy failed there and 
the destination dir was not behaving well.

Just deleted the erroneous destination folder, I renamed to something 
like "2010-june_providers" and retried from there on.

I have migrated a 3 GB account (mine) in this way.

For security I did not do "all at a time". I just moved 10 folders, upon 
finish 10 more folders and so on.

TB handles well if the destination folder exists. Example:

Supose I have:

old/2001 to old/2009

Spoose in the DST you already have old/1996 to old/2000

By dragging "old" onto "old" it will copy from 2001 to 2009 inside "old" 
at the same level than 1996 to 2000.

NEVERTHELESS IT IS TRUE that sometimes TB refuses to do the drag-n-drop. 
At this time, just close TB and reopen it and Drag-n-drop worked again.

Hope to help.
Xavi.
