Licensing question: Intermingling TLP and Retail Licenses of Design Standard 6

Hey everyone,

I have a VDI environment where users are running Creative Suite Design Standard 6 on a non-persistent virtual desktop pool. CS6 is installed directly on the desktop image. I have 5 seats under our TLP agreement with the same serial number, and 5 users.

Our company recently did a few acquisitions and onboarded some new users. These users run Creative Suite 6 DS as part of their job, and as part of the absorption we're bringing them into the VDI farm. Problem is, the existing copies their previous employer bought them were not under a TLP/volume license. Each user has their own serial number.

Will I be in trouble with Adobe if I take those retail copies of CS6 away from them, put them on a shelf, and added these users to the virtual desktop pool mentioned above? (This would mean they'd now be using our volume serial.)

Alternatively, is there any way to take a retail serial number and put it under the umbrella of our TLP/volume license?

Thanks!
