In order to move a DC from one domain to another you have to first demote it
from the current domain.  There is no way you can just up and move it, but
if you do this and there are no other dc's in the domain you are removing
from that domain then goes away, along with all the AD objects associated
with it.  Which means all users in domain a would lose access to all

What you may want to consider first is if you want to migrate all current
users of A over to B prior to the demotion of the dc.
