[Dovecot] Move of mail folders to other mail account on same server

[Jan Valvekens]

Hi,

I'd like to move mail folders from one mail account to another mail 
account on the same server. Moving the folders via my mail client 
(Thunderbird) takes a long time. Therefore I wondered whether it's not 
possible to simply move the files on the server itself.   If I 
unsubscribe to the folders in my source account, then move the folder 
and subscribe to the folders in my target account: will that work?

I run dovecot version 2.1.15

Thanks a lot,

Jan
