[Dovecot] Migrating existing local Maildir structure to dovecot server Maildir

[Halim Issa]

Hello,

I'm about to migrate a number of existing users who have been using
POP3 with emails stored locally in KMail's Maildir format into an IMAP
solution based on Dovecot.

Will it be possible to simply move all the KDE Maildir folders from
the local PCs to the Maildir folder on the IMAP server running Dovecot
and then have the emails accessible on the server, or will this most
likely mess up the Dovecot index files?

If this causes index file trouble, is there any way to force a
re-indexing of all these files, or is there another recommended way of
migrating up to 7 years of email communication from local hosts to the
IMAP server, for later putting them in folders?

Thanks in advance!

(PS. I noticed a few of the howto's on how to migrate to dovecot, but
they only focus on moving from mbox to dovecot or similar, and not
migrating existing Maildir emails to a new dovecot server... Any such
pointers would be greatly appreciated :-))
