Adding FAST Search to an existing SharePoint 2010 farm, you may notice that your existing site collections do not have “keywords, site promotion and demotion, user context” functions in the site collection administration section. Well there is a good reason for that…. The feature that activates these functions is not enabled. The feature ID is “5EAC763D-FBF5-4d6f-A76B-EDED7DD7B0A5″ . I had seen this behavior in my development environment but never tried to understand why. I would just create a new site collection and boom everything was back to normal. J A quick Google search found this blog. http://www.neilrichards.net/blog/?p=149 so thanks NEIL!

The only credit I can take is the PowerShell code below that enumerates through all the web applications and their site collections and activates the feature. Thanks
