Move exchange 2010 and DC to another existing domain?

Hi

 Please can some advise of the following.

 We have two companies. Company A & Company B.
 Company A setup:
 Have their own domain
 They have exchange 2010.
 Domain Controller 2008
 Sql server with an application.

 Company B setup:
 Have their own domain
 Have exchange 2003
 Domain controller 2003 & 2008

 Now we need to transfer company A to company B...
 All servers will be moved to company B but they still need to use Exchange A and sql application.

 Both exchange needs to work independently until such time that we merge both domains....
 How can I get this done successfully?

You cannot pick up Exchange from one forest and move it to another.
Therefore you have two options.
1. PST migration
2. Cross forest migration.

I would start with upgrading the company with Exchange 2003 to Exchange 2010 (which is the latest you can migrate to from 2003). That will make the cross forest migration much easier.

Cross forest migration is documented on TechNet, but an Exchange upgrade is enough to get started with.

If these are NOT SBS systems, create a trust between the two and keep things online, migrate services and features as needed.

Hi Guys

Thanks for your reply. Here is what I decided to do...

So what I have decided to do is create a new domain on our exchange 2003 and have our MX records point to it. SO mail will be delivered to our domain , no need for a trust, etc. as we are going to decommission the exchange 2010 and will upgrade later on.

As for the SQL server I will have to look into moving the server to our domain and try to use the application as it was used...Any advise on how to move an sql server?
