Over time the Reports Database in Password Manager grows too big and impacts performance & uses up disk space.
There is no functionality within Password Manager which will do a database 'Clean up' or 'Archive'.
From within Password Manager all that can be done is create a new database and then remove the old one from the SQL server.
From within MSSQL Server however, to lighten the load on the database, all entries older than two or three months could be archived and deleted thus reducing the size of the database.
An enhancement request has been submitted to include this functionality into a future release of PWM.
