You can do the following way also. We used to do it this way and worked
verywell for us.
This requires another NW server LIC.

1). Install Networker Server.
2). MMRECOVE or copy the RES, INDEX, Mdedia Database (MM folder)
3). From the command line NSRADMN -d (Path of the lic)
4). Delete the lic (since this will be the same as your production server).
5). enther the new auth code.
6). Start the server.

>From here on
Only copy the Index and MM folder on regular basis.
Any time a new client is created on the production server make sure you
create the client with the same client ID on the dev/DR/standby. This will
ensure the media and client indexes are in SYNC.
Now will have 2 identical systems if on goes down you can use the second
one.


coming to your question 3 How will the AD react?
I believe you have to delete the old Server from AD. B/C no 2 Servers cvan
have the same name unless the FQDN is different.

Hope this helps

cheers
