cyrusbdb2current <sasldb_old_path> <sasldb_new_path>
cyrusbdb2current converts the current sasldb database from BerkeleyDB format to the currently used database format. It is STRONGLY RECOMMENDED to make a backup of the current database before the conversion.
We expect that the old path is /etc/sasldb2 and the new one is /etc/sasl2/sasldb2
