conversione coordinate gauss boaga in etrs89 utm33

[Supercecco]

hello to all, after years and years in which I produced as built georeferiti in gauss boaga now I am asked to georeferire in etrs89 utm33....
I have dozens and dozens of elaborate planners in georeferiti dwg in gauss boaga and I do not know how to change reference system to please the client.
I asked the mouse who usually works for me, but nothing... (I will change topograph :-d)

Help! !

use autocad 2016
soon and thank you all!
