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