When I did it, the automatic detection seemed to work OK. The only problem I 
had was because I used procmail for delivery. I had to have a custom 
procmailrc for each user as I did their migration. For each user, when you 
finish their migration, you have to rename their ~/mail folder to not show 
dupes. In my case as soon as there was a ~/Maildir folder, dovecot started 
using it and made new indexes.
