In support tickets and in various forums you often read about problems with Shopware updates. It is not uncommon for the store (frontend and admin) to no longer be accessible after an update.

To avoid destroying the entire store or the customer's test environment, the update should check the accessibility of the frontend/admin at the end. If, for example, the browser returns an error 500, a rollback should be triggered to restore the store to its previous state.

Currently, the customer is often faced with an unsolvable problem in this case and loses a lot of time until the store works again.
