Exchange Server Edge Transport Reports Wrong Version

Exchange-2010-Logo-733341

Excited to get started on our Exchange 2013 installs, we started with the mandatory schema extensions using: setup.exe /PrepareSchema
FAILED
Oh CRAP! Not during the schema upgrade was my first thought. It failed because it said I needed to upgrade all my servers. I had run through all the requirements for co-existing an Exchange 2013 and 2010 environment including installing the Exchange 2010 SP3 update on every Exchange 2010 server role.
I start with my Edge Transport and run:

Get-ExchangeServer | fl name, admindisplayversion

Yep, it reports all servers at the SP3 level.
Next up is my Mailbox servers. Running the same command reports that my Edge Transport is still running SP2. What?
Long story short, you should/may need to recreate your Edge Subscription to get the version of your Edge Transport reported properly in the rest of the Exchange environment.
I used these commands:
Edge Transport

New-EdgeSubscription -File c:\edgesub.xml

Hub Transport

New-EdgeSubscription -FileData ([byte[]]$(Get-Content -Path "c:\edgesub.xml" -Encoding Byte -ReadCount 0)) -Site "YOUR SITE" -CreateInternetSendConnector $false -CreateInboundSendConnector $false

Problem fixed…moving onto setup.exe /PrepareAD
Stay tuned!
