Before retracting a SharePoint solution, it is best to deactivate the associated feature in each Site Collection. Here\u2019s a script that reports on which Site Collections have a feature enabled, and optionally deactivate the feature. This is easily adapted to Web or Web Application features as well. Best is to first get the SPFeature GUID, using get-spFeature CmdLet. Just flip the $Deactivate switch to $true to actually deactivate. Note any SPFeature not found will generate an error that a try\/catch clause will not catch. The quick solution is to capture my output into $OutLine, and clear the console and output the summary at the end of the run.<\/p>\n
