title: How can I identify missing features in a SharePoint site that has been restored from a different farm?
body: <p>I recently inherited an application from a developer who is no longer with the company. This application restores SharePoint sites from backups and extracts metadata and files from lists in the site. The application runs on a SharePoint server and uses the Microsoft.SharePoint assemblies in C# and VB.Net.</p>
  
  <p>The backups come to us from various outside companies, and some of them have custom features installed. SharePoint Health Analyzer shows a warning about "Missing server side dependencies". When I look at the report there is a lot of "[MissingFeature] Database [db name] has reference(s) to a missing feature..." etc. The previous developer was supposed to implement a check for missing features, but it is obviously not working. </p>
  
  <p>How can I identify features that the restored site references, but are not installed on the farm?</p>
  
  <p>Thanks!</p>
