If you would like to remove a Customer-ID from TapeTrack but keep access to the historical data, it is possible to hide Customer-ID's from display without needing to delete anything. This allows you to view all Customer data at a later date if required for reports or audits etc.

See Hiding Customer-ID's.

If you want to delete a Customer-ID you need to remove all dependencies (Volumes, Repositories and Media Types) first.
