What's the final step after migrating Exchange 2003 into 2007 ?

Hi All,

I wonder what is the final or proper steps that you need to do in order to successfully decommission the old Exchange Server 2003 from AD ?

at the moment I have successfully migrated Exchange Server 2003 into 2007 and mail is working fine.

However when I run Get-ExchangeServer it is still there but without role assigned ?

Ok, can i just select uninstall from the server ?
I am afraid to make changes in my AD server since I don't think there is roll back method in this case.

I suggest you turn off the server for a couple of days and confirm everything still works, like OAB download etc. If everything works then turn it back on, wait for everything to start normally and then select uninstall...
