I have migrated all data from a legacy Exchange 2007 SP3 server to a new Exchange 2013 server.  However, when attempting to uninstall Exchange 2007 SP3 from the legacy server as the final step of decommissioning it, the uninstall fails with the resulting error message:

   C:\>setup.com /mode:uninstall

   Welcome to Microsoft Exchange Server 2007 Unattended Setup

   Preparing Exchange Setup

   The following server roles will be removed
       Mailbox Role
       Hub Transport Role
       Management Tools

   Performing Microsoft Exchange Server Prerequisite Check

       Mailbox Role Checks              ......................... FAILED
        Cannot find at least one global catalog server running Windows Server 2003 Service Pack 1 or later in the local Active Directory site.

    Hub Transport Role Checks        ......................... FAILED
     Cannot find at least one global catalog server running Windows Server 2003 Service Pack 1 or later in the local Active Directory site.


   The Exchange Server Setup operation did not complete. For more information, visit http://support.microsoft.com and enter the Error ID.

   Exchange Server setup encountered an error.

I have a feeling this may be due to the 2003 R2 domain controllers having been replaced with Window Server 2016 DC's, and the Exchange server not being able to talk to them.  Is there something I'm missing?  Any suggestions for successfully installing the Exchange 2007 SP3 server, or do I need to do a manual removal and cleanup?
