Hi jody_lions and welcome to our forums
Yes, we can change the subscription status on your license but please note that we do not refund the price of the subscription.
Having a subscription on your Network licenses allow you to have license file which activate the 2013 version and the 3 previous of your product or Suite.
If you drop the subscription on 2 Network licences, you will need to have 2 separate license file if you need to work on previous versions.
Hope it reply to your question
