[Dovecot] Using DSync to convert from maildir to m/sdbox during migration of mail to new server

Ok, now to work out the precise method (config for the target server and 
dsync command) to use to perform the migration from the old server to 
the new one, converting to dbox (s or m, depending on how the other 
thread discussing this turns out).

I'll update the old server to 2.2.10 tomorrow morning so they're both at 
the same version.

So, assuming both servers are running 2.2.10, with

mail_location = maildir:~/:INDEX=MEMORY


mail_location = sdbox:~/sdbox
mail_location = mdbox:~/mdbox

After reading and re-reading:


I'm not so sure...

First problem - apparently it can only be used one user at a time? And - 
do you have to actually know the users password too?

If so, then this probably isn't going to be easier, and maybe even 
harder than just rsyncing everything, then slowly converting each user 
one at a time.


Best regards,
