Revoking a License
Thales offers you the freedom to purchase and apply upgrades to any HSM appliance you possess. If you have already applied an upgrade to an HSM appliance and want to remove it and apply it to a different HSM appliance, we refer to this process as revoking a license. Revoking a license permits you to transfer an upgrade from one HSM appliance to another. A simple use case is transfer of an upgrade from a development HSM appliance to a production HSM appliance.
A self-service feature to revoke a license is in development and Thales hopes to release it soon. Until that feature is released, you must leave upgrades installed as you distributed them across your HSM appliances.
