Not sure what you mean by that, care to explain ?

I think you mean that you only have one AD DC, a BDC is an NT4-style
backup domain controller and has nothing to do with AD.
I would use this as an opportunity to upgrade Samba to a much later
version (Samba >= 4.9.0), run this as an AD DC and convert the original
DC into a Unix domain member and use this as a fileserver, problem is a
DC will have different numeric IDs to a Unix domain member, unless you
are using RFC2307 attributes.
