i have an exchange server 2003 and windows server 2003 domain controller on a single forest.
i want to implement windows server 2012 and exchange server 2013. and then migrate the mail boxes from windows server 2003 to 2013.
Most recommendation are
1. Double Hop migration - Time consuming
2. PST - Multiple Errors
What i am thinking is to create a separate forest and do a cross forest trust
Question 1. how to i migrate the 2003 domain controller to the new windows server 2012 domain controller?
Question 2. migrating the mailboxes isn't much of a task to 2013 as i will be using a 3rd party software
Worries. Having a second forest and domain worries me, because the client still want to maintain the current forest and domain.
How do i overcome this.
