I thought this one was fairly well covered in the Migration docs in the 
wiki... IIRC it has to do with uid format.

http://wiki.dovecot.org/Migration/Courier

Aside from the warning at the top about bad migration causing re-downloads, 
there 'Dovecot configuration' section, and the one on "Old Courier POP3 
versions to Dovecot v1.0", cover settings for pop3_uidl_format.
