QQ - I got a new server 2019 image (previously used 2016) so i built a new RDS license server with same OS version (server 2019) which is activated and added to terminal services license server AD group. I installed Windows server 2019 Per user cals via the MS clearing house using the EA number and i plan on changing the RDS licensing GPO to point at the new RDS license server (FW rules are good) is there anything i have do with the old RDS license server / CALS ? do you have to return the old CALS or deactivate the server via the ms clearing house?
