Server Exchange 2003 migration

Hello,

What would you do?  Our situation:  We are migrating ABC to XYZ.  We have Server 2K3 environment with Exchange 2K3.  We haven't created XYZ yet.  
Do we: Create a new domain in the ABC forest, and leave Exchange in ABC, but have it work with 'smoke and mirrors'?
Or do we: Create a new forest, and migrate everything over?

Thanks,

First thought is, how many users, machines etc. do you have that would need to be migrated over?

Are we talking a hundred or so, or hundreds or even thousands?

Personally, for me, it would depend on the amount of leg work I would have to end up doing as well as any other business type requirements (meaning, is their some specific reason we should to this over that because of how it might affect something).

What is your time frame?

Lets start there.

Well, our name is officially changing july 1, we plan on changing the domain the last weekend in june.
We have less than 100 users.
We won't be using the old domain for anything once our name has changed, so if we create a new domain, it'll still be in the abc forest....

Thanks.

Based on your timeframe and what you need to acomplish, I would go with what you said in your first post:

Create a new forest and migrate everything over.
That will give you the 'cleaniest' setup without having to do 'smoke and mirrors.'

That is what I would do. Might be a pain to do initially, but in the long run, I think it will pay off and you will be happy you did so.

HTH.
