dovecot - Sep 2011 - BestPractice to migrate imap mailbox from one machine to another

Hi list,

currently I use dovecot v1.2.15 with maildir++ mailboxes. (Debian 
Squeeze)
I want to set up a different server with dovecot v2, also maildir++ 
mailboxes. (also Debian Squeeze)

What is the best way to copy the existing mailboxes from the older 
machine running dovecot v1.2.15 to the new naked machine?

Greetz, Tobias

ok, but this tool is not free of charge.
Are there any known problems just copying the mailboxes with scp or 
rsync?

I did the same thing, with no know issues so far.

My old server was running dovecot 1.2.x and i coppied the whole maildir 
structure to the other machine.
Then started Dovecot 2.x and all was fine.

Should be the same as instlling 2.0 over the old 1.2.x version, then it 
uses the old maildir also.

Well test it i would say.
Just do the copy, and try if everything works.
then do it for a final migration.

? you should donate
but you can use it without too, i.e its part of ubuntu

may work too,
with few problems depending on your setup, but its no real way if you
make migration on the fly in my eyes

better setup the new server, do tests, make imapsync

Oh, cool, thanks for the hint. Yes, I will test simple copy, imapsnc 
and dsync.
Thanks a lot.
