Merging two Companies with 2003 Active Directory to 2012 Active Directory

Last Modified: 2015-03-01
I have the following situation:

1. Company A (a .local domain) with 2003 Active Directory and hosted Exchange 2010 Server
2. Company B (a .local domain) with 2003 Active Directory and local Exchange 2003 Server

Company A is merging with Company B - and we would like to have an entirely new .local domain with a Windows 2012 Active Directory Domain Controller, and Office365 Exchange server.

There are SO many variations of this problem here - that I'd just like to get a start going in the right direction.  I want to continue to allow users to have access to the network shares that they currently have access to as well (Company A has a NAS server, Company B has a Windows Storage Server).

Can someone help me get started?
