How to remove a subscription key from an instance?¶

Let's say, you want to duplicate your instance by copying a VM and use the duplicate as a sandbox (or a test server), but you don't want to have user limit applied based on your subscription key. The solution is to remove the subscription key from an instance in your duplicated VM using the following OCC commands:

php occ config:app:delete support subscription_key
php occ config:app:delete support last_response
php occ config:app:delete support potential_subscription_key
