[Samba] Migrate and Update (Samba 4.1 ADDC to Samba Latest Version on different Server).

[Juan Ignacio]

I come here to say we have finally gotten rid of the old production server
with samba 4.1.

We already demoted it and turned it off where he slept for the rest of
eternity.

Now the domain is all virtualized with several DCs and with replicas on
multiple servers.

I want to thank all the Samba team for the help and especially Rowland who
always had the patience to explain or remind me of things.

For now I just have one thing to solve, don't know why I have 3 dns entries
for the domain that aren't correct here, what is the best way to remove
those  Unknown  and duplicate entries  .

root at dc2:/var/lib/samba/private# host -t A ourdomain.org
ourdomain.org has address 100.200.12.5 (DC2)
ourdomain.org has address 100.200.12.6  (DC3)
ourdomain.org has address 100.200.12.95 (Unknown)
ourdomain.org has address 100.200.12.6 (DC3) ? duplicated
ourdomain.org has address 100.200.12.3 (Unknown)
ourdomain.org has address 100.200.12.7 (DC4)

Thx again.
