Hello, I'm trying to move to one Samba4 AD from a windows 2000 server, and I'm currently trying this: - adding a win 2003 server to active directory - adding a samba4 server to active directory thanks to the windows 2003 server. - moving roles to samba4 - switch off windows 2000 and 2003 Is it the best way to do? Do I try to transfer or seize the 5 roles? Do I need to do an additional task after switching off the old servers ? thanks for helping! :) Samuel
