[HowTo] Replace courier with dovecot

[tera]

I've got a problem with the passwords.
I builded up ispCP 1.0.3 on a new server and use now dovecot instead of courier.
This should be the new one for replacing my old ispCP 1.0.2 with courier.

Instead of migrating from a to b I reconfigured everything completely at the new server and copied all the encrypted passwords from the old database to the new one.
Now all the mailpasswords doesn't match.
I also tested it with setting the known password in the old ispCP again and copy it again to the new database - doesn't work.
When I set up the same password again for the mailaccount in the new ispCP with dovecot it works...

How am I able to 'refresh' all my old passwords to the new system?
