The migration of process instances and tasks will not transfer teams or manager teams to a new snapshot context when a team filter service is used. The teams associated with a task that utilizes a team filter service will block the deletion of the snapshot where the task was created.
We are using a variety of toolkits that allow for the reuse of service flows across multiple automations. Therefore, when deploying a version of an automation, we not only include the snapshot of the automation but also the snapshots of all its required dependencies. Our security system relies exclusively on team filter services, meaning that every time we need to update an automation, it results in 10 new snapshots. After process and task migration, as some tasks can remain active for weeks, months, or even years, we are accumulating more and more snapshots on our platform, leading to performance degradation and warnings.
Our goal is to be able to delete old versions of snapshots by ensuring that teams are switched to the latest snapshot version, allowing for proper maintenance and efficient platform operation.
Example of error we have when trying to delete an old snapshot, where there is no active task after migration, but where some adhoc groups were created.
