Hey @efehn - just to clarify are you referring to Alteryx Designer or Alteryx Server?
For Designer, I don't think that should be an issue. You can either deactivate and then reactivate the license yourself or reach out to our fulfilment team at email@example.com for assistance after you've conducted your tests.
If this is regarding Alteryx Server I would advise you post this to the Server Discussion boards here.
If this answers your question, please mark this post as a solution such that others can also benefit. Otherwise feel free to reach out if you have any further questions.
