Did you actually deleted the exchange server for which you are running upgrade?

  Since you have deleted the exchange server on which upgrade had to be done. Now uninstallation will also not succeed properly since the actual server container in ADSIEDIT has been removed. Whether its installation or uninstallation the setup looks at the server container in ADSIEDIT and this server container is also replicated on all DCs.
  
  So now you will have to do a manual exchange uninstallation. You can follow below article for manual exchange cleanup and then setup a new exchange install if you require.

    I've deleted :
    
    CN=Configuration,DC=DOMAIN,DC=LOCAL
    CN=Services
    ->; DELETE
    CN=Microsoft Exchange
    CN=Microsoft Exchange Autodiscover
    
    Here I did not find an exchange server in groups and objects
    
    CN=Default naming context,DC=DOMAIN,DC=LOCAL
    ->; DELETE
    CN=Microsoft Exchange Security Groups
    CN=Microsoft Exchange Security Objects
    
    in the registry all deleted (MSExchange*), directory removed
    in IIS Manager all deleted
    
    and again stopped installation at step 7 (as in the screengrab above)
