I performed a migration from exch 2010 to exch 2010 (new hardware).

I followed these steps: http://blog.shiraj.com/2011/11/how-to-upgrade-single-server-exchange-2007-to-exchange-2010/

My question is:  Is step H:  accurate.  should I just go into control panel on the old server and remove the old exchange 2010?

The old exchange is on the Active Directory box (I know, bad practice) so cleaning up DNS entries could get messy and I don't want to delete anything that will impact AD.

Any word of advice would be greatly appreciated.

both are physical servers running Windows Server 2008 R2.

Are you completely decommissioning the old server or just taking exchange off of it?

Step H is correct in that once you've completed your migration you finish the removal by uninstalling Exchange through the Programs applet in control panel.  Part of the uninstall handles the removal of all of the objects and references for exchange from active directory.

You'll want to review your systems once it completes just to make sure you're good but generally if you've properly moved everything you should be ok.

I don't think you'll need to manually remove anything from DNS unless the uninstall fails or you've manually added custom pointers or objects yourself.

Ok then you should be fine.  If you get any errors or if the uninstall fails just post back with what errors you got and whatever log information you have.  

Like I said though if you've followed the steps and migrated everything properly then you should be in good shape.  You've already done the "hard" part.

Oh... and I'm not sure why it says to DCPROMO the box but if you're only removing Exchange then you definitely don't want to DCPROMO...
