In our testing environment, we have installed evaluation version of TEM (and choose express option for database) on one of our windows server.Since the license expired we have taken the back up of database and installed same evaluation version of TEM on other server and restore database.but the restored clients on new server are still offline.
Evaluation versions of TEM will only last for 30 days… Backing up the database and re-installing will not help because the license and digital signature information is stored in the database. You will need to re-install from scratch.
You should get a production version of TEM if you want to run it for longer than 30 days.
