Courier and dovecot implementations use a different maildir layou, so you can not simply switch the imap daemon. If you want to migrate your server to dovecot, you will have to create a new "Maildir" subfolder in every ecisting maildir and copy all the contents of the existing maildir into this new subfolder. Exa,ple:

Courier layout:


Dovecot Layout:


If your users have created any mailfilters, then these filters will get lost as they are written in maildrop syntax and not sieve as required by dovecot.
