Yes, sorry for that. What I meant was: Currently I am setting up a file
server together with AD DC, which is not recommended, but given my
simple scenario it is ok to do it that way, at least is what I
understand. My question was: Once I have proper hardware resources to
have a file server separated from the AD DC, how easy will be to migrate
the configs/shares from the AD DC to the separated file server (Domain
Member)? Makes sense now?

Ok, how can I verify? How about the other groups? By other groups I mean
the ones I am creating as my company departments, like Commercial,
Marketing etc, so I can create shares per department.

Is there any wiki I could follow to do one of the above? Thank you

Could you give an example please?

Thanks for the explanations, how do I create this new group? With groupadd?
If you can give a full example, I will be very glad! But please don't
think I am lazy, if there is a wiki that mentions how to do it, just
point me to it :-)
