Reconfiguration of RDS (Windows 2012 R2)

Hi

I have such RDS farm configuration

• sev1 - RD Session Host
• sev2 - RD Connection Broker, RD License server
• sev3 - RD WEB Access server

I want to move all roles from sev2 and sev3 to sev1

To move WEB Access role I want to add Web Access role to sev1 and then remove sev3 from RDS farm (I have tested this and its worked)

For License server there is migration wizard so it should not be problem.

But how to move RD Connection Broker to serv1 server and remove old? I can not find any solution to do this ?

Any tips would be very helpfully ?

Thanks in advance
