Currently have a production Presentation Server 4 environment with a 2003 server acting as the Terminal services Licensing server in per user mode. I am rolling out a 2008 R2 Xenapp6 farm that will replace the PS4 farm and will have a 2008 R2 licensing server.
My problem is I need to get the licensing working on the new Xenapp6 farm while maintaining the PS4 production farm until we migrate over. I posted a previous question about this and was told to activate a new 2008 R2 licensing server and call the clearing house to get 2008 CALS issued (I have software assurance). I was told to leave the existing 2003 licensing server up and running until the migration is complete then I can just shut down the server.
When I call the clearing house they require me to de-activate the current 2003 TS licensing server, remove the licenses and then they will upgrade the 2003 CALS to 2008. This will obviously break my current production environment. I have about 70 days left on the evaluation licenses. Am I going to be forced to migrate in this time frame? Seems a little unreasonable. For Citrix, I have one license server that is passing out licenses for both the Xenapp6 farm and the PS4 farm. Can I upgrade the CALs, move them to the 2008 server and have it service my production 2003 environment as well and the 2008 environment?
One other note. For a while I had no 2003 terminal Services licensing server in my 2003 PS4 environment. I believe the machine crashed and I had to re-install it from scratch and did not realize it was the 2003 TS licensing server. I did not notice because the PS4 environment never missed a beat. Apparently if the servers are in per user mode they only check for the Existence of a TS licensing server when they are first set up. Then they never check again unless you make a change. Could I move everything to 2008 and leave these per user server running without a license server until I am migrated over? I guess I could test this by stopping the 2003 licensing server and see what happens.
