I assume I should maybe move the FSMO roles at *first* ? The DC to be
removed here was the initial DC so it has these roles assigned.

After that I would add DC3, let it sync etc ... then demote DC1 and
after tests with DC2 und DC3 (DC2=DC1new, DC3=DC2new ;-))
scratch/archive DC1:/var/lib/samba and set up a DM on that hardware
based on the same smb.conf as on the current first DM/fileserver.

All this will happen in a few weeks or so, time enough to think about
it, prepare and enjoy the thrill :-P
