Exchange 2010 Edge server shows previous version

Question

I have an Exchange 2010 environment with the Edge role installed on TMG and its working fine.  All servers have had SP3 installed and rebooted.
I am trying to introduce my first Exchange 2013 server into the environment but the readiness check tells me not all the servers have SP3.  On the Edge server it shows SP3 is installed but from all other Exchange servers it shows SP2.
Any ideas?
Thanks

For anyone else wondering.  I've done this in my lab, and I didn't have to remove the old subscription, just export the file from your edge server, copy it to any server running emc internally and import it, then force a sync and the version should
update.
On edge server open exchange
     powershell and run New-EdgeSubscription -FileName
     "C:\EdgeSubscriptionInfo.xml"
Import edge file
     into new server
You
need to be assigned permissions before you can perform this procedure. To see
what permissions you need, see the "EdgeSync" entry in the
Transport
Permissions topic.
In the console tree, navigate
     to Organization Configuration >
Hub Transport.
In the result pane, click the
     Edge
     Subscriptions
     tab.
In the action pane, click
New Edge
     Subscription. On
     the New Edge Subscription page, complete the following fields:
Active
      Directory site   Click
      Browse, and then select an Active
      Directory site in the drop-down list. This field identifies the Active
      Directory site where the Hub Transport server is connecting to the Edge
      Transport server for which the Edge Subscription exists.
Subscription
      file   Click
      Browse, and then select an Edge
      Subscription file.
Automatically
      create a Send connector for this Edge Subscription   Select
      this check box to automatically create a Send connector that routes
      messages from the Exchange organization to the Internet. The Edge
      Subscription is configured as the source server for the Send connector.
      The Send connector is configured to route messages to all domains by
      using Domain Name System (DNS) MX resource records.
Click
New to create the new Edge
     Subscription.
On the
