New Job, new DNS challange, need advise.

[Scott Tasem]

I just started a new job. My company has a DNS challenge and I'm not sure
how to address it.

We have a DNS server running linux with a DNS zone called, company.com. We
have a second DNS server which is Microsoft AD intergrated which is
123.company.com. 123 is my AD Domain name.

My CIO, wants to remove the Linux DNS server and collapse DNS with little to
no down time.

I know I could migrate to an entirely new DNS zone, but I wanted to know if
there are any suggestion on how to migrate without creating new?

So my net result is company.com with a child zone of 123.company.com on
my Windows DNS server.


thank you in advance for your advise.

What was the Linux server used for hosting company.com? Public records or
something for internal private records? If external, you don't want to host
your external zone on a DC's DNS. There will be a conflict of private/public
data besides the fact of exposing it on a public untrusted network.

I also meant to ask, how large is the current network, meaning how much data
is in the123.company.local zone from your internal machines? Is here 10, 20,
100's, 1000's?

You can create the company.local zone on the current DC/DNS but it may lend
to a dupe zone. Depending on the size and number of DCs, etc, you can change
the AD current zone to a primary zone, then create the company.com zone,
then create a '123' child zone under it. Then go into the zone file in
system32 and copy the data from the 123.company.com into the company.com
text file, and reload the zone then change it back to AD integrated. This
way you can consolidate them into one. You can also just simply create the
company.com zone under FLZ.
