Long time back someone had created our domain with single label dns called xyz. and within dns there is a zone called xyz.com
Now that we have decided to migrate this domain/AD into a new greenfield forest/domain, the company wants to keep the new name as xyz.com but there is already a forward lookup zone with this name in the current single label dns domain (xyz.)
Will it be an issue if I create a new domain called xyz.com and this by default creates xyz.com forward lookup zone. So at least till we completely decommission the old domain there will be 2 forward lookup zone with same name called xyz.com in 2 different domains
Is xyz.com the same as your companies external dns (like for the website)?
If so use ad.xyz.com it’ll make it so much easier.
If you HAVE to use xyz.com you’ll need a new naming convention for anything registered in DNS (I.e all devices/servers/computers etc).
How are you going to move the users over? Creating them two accounts? Cause you won’t be able to use trust relationships temporarily if your ad domains are called the same thing.
