Processing Engine

If you are upgrading from Sitecore XP 9.1.0 or later, before you start the upgrade, we recommend that you review the list of tasks in the ProcessingEngineTasks database in the Tasks table and:

• Wait for all the ongoing and pending tasks to complete.

• Stop scheduling new processing tasks.

• Ensure that there are no more tasks in the queue.

  If you do not wait for the ongoing tasks to complete, when you restart the Sitecore Cortex Processing Engine Windows service after the upgrade:

  • Ensure that any deferred tasks that are in the InProgress state are re-run.
  • Ensure that any distributed tasks that are in the InProgress state continue from the point they were at when you stopped the Windows service.
