Update an add-on

The steps that you use to update an add-on depend on whether the add-on is a traditional add-on, or a standalone add-on.

Traditional add-ons are linked to a specific subscription. If you cancel the subscription, the associated add-on is also cancelled.

Standalone add-ons are not linked to a specific subscription. Standalone add-ons appear as a separate subscription on the Subscriptions page (or on the Products & services page in the admin center (preview)), and have their own expiration date.
