Migrate Windows Server 2008 RD TS/RDS Per Device CALs from a 2008 r2 RD License server to a 2012 RD License server

I would like to migrate my 2008 r2 CALs from current Server 2008 r2 to a Server 2012 RD License server.  Will the Migrate licenses Wizard in 2008 r2 Licensing server work for this or is there another process that I will have to use?
