Mail migration help


I have been given the task of migrating 120 users to a new Exchange server and domain.

The change is needed as our sister company and us are merging  into one.

There are two domains in question lets call them *sister.com and *brother.com.

*brother.com users will be changing there addresses to sister.com addresses. However still need to be able to send as *brother.com once migrated.

The 120 *brother.com users are split up in 7 different countries in the world. I need to d o a phased transition for all users to the sister.com domain with little interruption. .

Chances are I will do 2 countries a week.

My initial plans are this -

Create all brother.com users on the sister.com mail server with sister.com (as default) and brother.com as an alias.
Point the MX record of brother.com to the sister.com mail server
Create a domain called brother1.com and assign it as an alias for all users on the brother1.com exisiting mail server.
Forward all e-mails for brother.com users to brother1.com
Migrate users (phased approach)
remove forwarding rule once user has been migrated..

Can anyone see any problems with my plan?

You dont have to create a domain ... simply create a Email\recipient Policy with those domain email address
