Yes the setup is broadly the same but you only ever extend the schema once. The other thing is the first instance you create will be the Primary other sites can normally be Primary too but now you join the site you created.

I just re-read your question actually: are you sure you want TWO ConfigMgr instances at all?
The reason I ask is that it is not necessary unless there are political/control issues. Normally you can just install ONE Primary Site instance and then get the two CM systems to talk using that a network access account is configured, so the client can access the resources.

Forget what I said about joining the existing site. That does not apply in your situation I think.

Please see a very similar question here:

In short, you can see client machines from the original domain using the trust, by adding an account. Then you can use client push to install the agent in the new domain. See Peter's article here:
