How do I migrate emails and accounts from one exchange server to another?

The exchange sever in 1 domain: exchange.1.com is the source server which contains email accounts and emails. The target exchange server: exchange.2.com. Both email servers reside separately in their respected domains. At this point exchange.1 is forwarding to exchange.2 & the question is: what's the easiest way to transfer these accounts plus email to the exchange.2?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.
