Hi,

in general workflows run smoothly after a migration / upgrade. What you can do is verify that the most critical workflows can still be run and also the most critical forms can still be opened and saved. Especially forms that work with managed metadata should always be looked at to see if the connection to the managed metadata service application made it to the new environment.

Besides this there shouldn't be anything to do unless workflows start and run as before.

Best regards

Enrico
