Sage 50 - Azure - Testing

Solved

I have a customer that uses Sage 50 (Quantum 2024), on-prem, currently with an outdated Win 2012 server. 
I want to set them up in Azure and parallel test for a month or so. 
Will I have any issues re-using their serial number on the Azure instance? 
I'm not looking to violate any license agreement, just want to test and migrate as necessary. 

Thanks
Lonnie
