By default only two concurrent active rdp sessions are allowed on a windows server editions like 2012,2016 or 2019. If we need more than two users simultaneously log into the server we need to have Remote Desktop Licensing (RD Licensing), formerly Terminal Services Licensing (TS Licensing), which manages the Remote Desktop Services client access licenses (RDS CALs) for users to connect to a Remote Desktop Session Host (RD Session Host) server. If we enable RDS CALs, each user and device that connects to a Remote Desktop Session host needs a client access license (CAL). The RDS CALs is installed as a server Manager Role. There is a default licensing applied on installation and activation with a grace period of 180 Days during which no purchased RDS CAL license needed. After that we need to choose either of below Licencing model and need to Purchase it from the Microsoft store or from a vendor. RDS Per Device CALs :

How to Remove RDS CALs from a RD License ServerSome times we want to transfer our RDS CAL license set from one Remote Desktop licensing server to another, in such cases we can remove installed CAL licenses pack from the current licensing server using two methods.
Use the following cmdlet, and list all the installed RDS CAL packages on the server. Find the KeyPackID value for the RDS CAL package that you want to remove and run the command. We can get the KeyPackID value from the Remote Desktop Licence Manager Itself. 2. By Removing the RDS CAL database file. To do this, stop the Remote Desktop Licensing service from the Windows Services section Rename the file C:\Windows\System32\lserver\TLSLic.edb to C:\Windows\System32\lserver\TLSLic.edb_bak and start the “remote desktop service” again.
