As you probably know, in SCOM 2012, there is no RMS role anymore. For keeping backward compatibility with some management packs that required the RMS role, Microsoft created the RMS Emulator role.

By default this role is hosted on the first management server that you installed.

As you can see, SCOM2012.vnext.be server is hosting the RMS Emulator role. This is confirmed by the following PowerShell command : GET-SCOMRMSEmulator command-let.

Now, if you want to move this role to another, simply execute the command : Get-SCOMManagementServer -Name "NewServerThatWillHostRMSEmulatorRole" | Set-SCOMRMSEmulator

You could confirm the move of the RMS Emulator role by retyping the command : GET-SCOMRMSEmulator

Or by looking on in the SCOM Console :
