Windows Active Directory Domain Name change and Exchange 2010?

I know a domain name change is unsupported when a domain contains Exchange Servers, but does anyone have experience with what will break?  I only have one Exchange 2010 Server in my domain.  I've done a single server/domain lab name change and the exchange services appear to be still working post name change but of course this was a simple test.

And yes, I am aware I can save all the exchange data and rebuild the exchange server after the name change, but was kind of hoping to avoid that.

Renaming a domain controller requires that you first provide a FQDN as a new computer name for the domain controller. All of the computer accounts for the domain controller must contain the updated SPN attribute and all the authoritative DNS servers for the domain name must contain the host (A) resource record for the new computer name. Both the old and new computer names are maintained until you remove the old computer name. This ensures that there will be no interruption in the ability of clients to locate or authenticate to the renamed domain controller, except when the domain controller is restarted."

"...every member computer joined to the renamed domain needs to be rebooted twice.."

Thanks.  I find it so frustrating that you can do a domain name change - as long as you aren't running any Microsoft Server products in the domain...  You'd think that Microsoft could have designed for this by now.
