[Dovecot] courier to dovecot

[Grafibit Rendszergazda]

Dear All,

I know there were many threads on this topic. I was searching the archive and 
the net also, but did not find a solution on my problem. I hope you can help me.

I am migrating from an old server using courier to a new server with dovecot and 
i can not manage to have the same uids after the migration.

After copying the message files from the old server to the new, and executing 
the script from the wiki page the messages are still re-downloaded by the mail 
clients.
After telnet and logging in to the old server port 110, I got the following on 
the command *uidl*:
1 UID377-1278276092
2 UID387-1278276092
3 UID394-1278276092
4 UID498-1278276092
5 UID499-1278276092
6 UID564-1278276092

On the new server i set up the *pop3_uidl_format = UID%u-%v* because it seems 
for me that the old server is using the same uidl format.
Either if i execute the /./courier-dovecot-migrate.pl --to-dovecot --recursive 
--convert /command or i don't the uidls on the new server won't be the same. 
Both the %u and %v numbers are differ.

Please give me any hints how to continue the investigation to have a successful 
migration.

Thank you in advance,
Tamás
