We recently came across a scenario where we had to upgrade Forefront TMG Standard edition to Enterprise edition, it is a very simple procedure and you don’t lose any configuration such as Rules and Network Config.

Steps to Upgrade

  1. Open TMG Console
  2. Choose System
  3. Press the System Tab
  4. Right Click the server to upgrade
  5. Click product ID Tab and choose upgrade to Enterprise Edition
  6. Enter your Product Key and then apply the changes and you’ve Upgraded successfully!
