This is so that dovecot not only treats the files under
/var/spool/imap/$USER as user's mail but too mboxes in his home

If you have concerns you could break something critical, it is always a
common way to test before with a test installation. Do it here too and
follow the indicated steps. It is indeed very simple.

Just yesterday I added some instrcutions in the dovecot wiki:


There is too a link to more details about the migration.

It will spit out conflicts.

You could if you force the dovecot install and you change the IMAP/POP3
ports uw-imapd uses in the /etc/services file. uw-imapd is xinetd
controlled on Fedora, so uw-imapd and dovecot could run in parallel with
using different ports. But I do not recommend this way, because you will
get a lot of horrible problems if mailboxes are used through both

Do yourself a favour and migrate in one step.
