[Dovecot] hard link between courierimapuiddb and dovecot-uidlist?

Hi, guys.

I'm attempting to transition between Courier IMAP and Dovecot. I may not be able to transition all the courierimapuiddb files instantly or even transition all my servers at the same time. Ideally, it wouldn't matter. Users can login and get to a Courier IMAP machine or a Dovecot machine and read their email (all mounted via NFS).

My question is: is there any reason I can't just do a hard link between courierimapuiddb and dovecot-uidlist? That way, I can transition users over to Dovecot at my leisure. And, if I need to, I can move back to Courier. The hard link is essentially free and lets me make sure these files stay synced.

Thanks Jeff
