I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server"
I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck.
My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header..
It doesn't matter if the client hasn't seen the X-UIDL header, because it's Dovecot that uses it.
The problem is anyway that your mbox -> maildir conversion didn't preserve the UIDVALIDITY and UIDs. I'm not aware of any existing conversion script that can preserve them.
