Possible to reacreate mail and ftp password-files?

You forgot to copy the keys as explained in step 5 of the upgrade procedure. The *db-keys* files store the keys used to encrypt passwords inside the database. Hence, as you forgot to copy the old keys they were replaced by new ones, and decrypting old passwords with the new key returns garbage instead of the original password.

If you have backups of the old keys, then you just have to restore them and re-set the passwords of the newer accounts (the ones you've changed after update). Otherwise, you will have to change all passwords from all accounts....
