You still are not giving us enough information, how was Samba running on 
the old NAS ?

If it was running as a DC, then you should have 'joined' your new DC to 
it, instead of creating a new DC and domain.

Active directory uses SIDs to identify objects (users, groups, computers 
etc) in AD, The domain SID will be in this format:

S-1-5-21-xxxxxxxxxx-yyyyyyyyyy-zzzzzzzzzz-RID

Where 'xxxxxxxxxx-yyyyyyyyyy-zzzzzzzzzz' is a set of random numbers, 
random per domain that is, each AD domain has a unique SID. The RID is 
again unique in the domain. This means that whilst you could export the 
users etc from your old domain, you could only export usernames etc, you 
cannot export the SIDs. This means that any machines joined to your old 
domain, will need to be joined to your new domain.

As for the Windows DC, it should be possible to join it to your Samba AD 
DC, but it is a bit experimental at the moment.
