Combine license of an unused environment with existing UAT environment

We have an unused environment with 400 AOs, it was for a Proof Of Concept for a client and they decided not to continue with that. We would like to combine this with our current UAT environment which also has 400 AOs and we are running out of AOs there, so we would like to combine them to have UAT with 800 AOs. Does anyone know if this is possible at all and who will be best to speak to about this?

Hi Elize,

Best thing is to talk to your OS account manager.
