Hello @Takami Chiro
- We need to reinstall and reconfigure the RDS role on the upgraded server.
- If the license server is separate, You might need to check RDS CAL version compatibility first:
License your RDS deployment with client access licenses (CALs) | Microsoft Learn
If you have RDS CALs that were directly installed on the same server that is being upgraded from Windows Server 2008 to Windows Server 2019, you will need to acquire new RDS CALs for Windows Server 2019 to be compliant with licensing requirements.
It is suggest to consult with a licensing specialist to ensure compliance and accurate information based on your specific licensing agreements.
Here by ‘broker’ do you mean ‘Remote Desktop Connection Broker’ ? Remote Desktop Services roles | Microsoft Learn
