Ladies & Gents,
I am trying to upgrade from Exchange 2007 to Exchange 2013 and keep failing the readiness check to begin the install. Here is the error I am receiving pasted below.. (We don't have any 2000 or 2003 exchange servers on our network or still as a system in active directory. I suspect maybe our small business server wasn't properly removed originally)
One or more servers in the existing organization are running Exchange 2000 Server or Exchange Server 2003. Installation can't proceed until all Exchange 2000 or Exchange 2003 servers are removed.
