Deleting Existing Permanent License Keys of SAP HANA Database

It is possible to delete all existing license keys in an SAP HANA database. This can be helpful if permanent license keys with an incorrect installation number or incorrect system number were installed on the database. Deleting existing license keys results in a lockdown of the database. The

installation of a new, valid permanent license key is required to unlock the database.

Make sure you have system privilege LICENSE ADMIN before proceeding.
