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.

Although either way would work id upgrade the AD first then migrate exchange.

Hope that helps!

As mentioned above both way you can do.

Exchange2007/2010 is tightly integrated with AD

You install 2008 AD and transfer all the roles to the newly installed server.
http://www.petri.co.il/transferring_fsmo_roles.htm
Then change the DNS IP in exchange 2007 and run the command 'setup.com /prepareAD'
After this command you have to make sure your exchange2007 is error free
configure the new AD IP in exchange2010 network settings (DNS IPs)
Start Exchange2010 installation  http://www.networkworld.com/community/node/47778
Move all your mailboxes and Public folders to exchange2010
Then decommission exchange 2007 http://technet.microsoft.com/en-us/library/bb123893(EXCHG.80).aspx
Make sure your exchange2010 is error free

Or

You can install exchange 2010 http://www.networkworld.com/community/node/47778
Move all the mailboxes/Public folders to exchange2010
Then decommission exchange 2007 http://technet.microsoft.com/en-us/library/bb123893(EXCHG.80).aspx
Install 2008 AD and transfer all the roles http://www.petri.co.il/transferring_fsmo_roles.htm
Change the DNS IP in exchange2010 server to the newly installed AD
Then run this command 'setup.com /prepareAD'
Make your new exchange2010 error free


Note: Be very careful when transferring FSMO roles. Using the Ntdsutil utility incorrectly may result in partial or complete loss of Active Directory functionality.
