You can't move your CIM installation to a different machine by copying the database files. The process for moving to a new machine is essentially the same as the process for upgrading to a new location.
Essentially, the process for moving your CIM installation is:
Use cov-admin-db to backup the CIM database on the old server.
Install CIM on your new server.
Copy the database backup file to the new server.
Use cov-admin-db to restore the CIM database on the new server.
