Backup Exec 2012 Central Admin Server

Hello all,

i want to know if it is possible to manage backup exec 2010 mediaservers with a 2012 central admin server ? (both are installed as a trial)

I´ve tryed to add a 2010 server to the 2012 CASO but it doesn´t work

Error: The server xxx does not appear to be a valid central administration server

thanks in advance
