FeatureAdmin is a tool for SharePoint administrators and developers to manage SP features. It can find and clean faulty FeatureDefinitions and orphaned remainders.

The Feature Admin Tool finds faulty activated features or missing feature definitions and cleanly removes them. It finds feature remainders in sites, SiteCollections, WebApps and in the Farm, caused e.g. by forcefully uninstalled Features from a farm without deactivating them before. These faulty features are not visible, but they cause errors, e.g. during migrations.

The Feature Admin Tool is able to identify and remove them. Very useful for major version upgrades e.g. to 2016 or 2019, or for downgrades from Enterprise to Standard.

But the FeatureAdmin can not only clean or uninstall, it also supports (bulk) deactivation, (bulk) activation or upgrade of features with any scope up to farm wide. This is ideal, for activating or deactivating features in large farms with many sites and/or SiteCollections.

FeatureAdmin is open source. The first version was introduced on CodePlex in 2009. For further details, please also visit our GitHub repository.

For version 3, the code was completely rewritten
