Problems with upgrade to 4.9

Hey everyone,

first of all thank you for this new release!

I encountered different problems during the upgrade process:

  1. The upgrade from rabbitmq from 3.13 to 4.0 requires an additional step: Execute rabbitmqctl enable_feature_flag all inside the rabbitmq container before you shut down the container stack before the upgrade. See Upgrading RabbitMQ | RabbitMQ for more information.
  2. I get some errors upon upgrading my workflows: AttributeError: ‘Workflow’ object has no attribute ‘get_state_initial’. I read in the release notes that workflows need to have an initial state before they can be initialized but I did not expect that it also causes an upgrade to fail. I will check my workflows and try the upgrade again. EDIT: My workflows all have an initial status set. So this might be a bug?

Ok, I finally upgraded successfully. Most likely the problem was, that I had documents for which workflows were not yet started. I tried to start the workflows with the corresponding tool but the workflows were still not started so I had to start them manually which worked. Luckily there were only about 20 documents so it was ok to do that manually.

Hi,

Improved the workflow migration 0037 to handle this edge. New release build pipeline is already running and he new version will be available in a few hours.

Thank for the report!
