MOSS2007: How to Remove Orphaned Features Using PowerShell

MOSS2007: How to Remove Orphaned Features Using PowerShell

I recently had to use content deployment on some old MOSS 2007 systems. These systems are alive for a long time and a lot of solutions/features have been deployed to them. 

If features are not deactived before removal they stay as an orphan in the system (contentdb) and can cause issues lateron. I had to cleanup orphaned features before the content deployment worked properly. 

The procedure for identyfing and removing orphaned features is quite straightforward:
  1. Go through every site collection and site recursively
  2. For each SPWebApp, SPSite and SPWeb
  3. Iterate through the *.Features collection
  4. For each feature, if the definition is null the script removes it from the feature collection 

** Use this at your own risk **

03.function ListFeaturesAux($header, $features, $obj, $boolremove)

06.    {
07.        if( $feature.Definition -eq $NULL)
08.        {
09.            write-host "Missing feature definition (feature id:" $feature.DefinitionId  "), Scope: "  $header
10.            if( $boolremove -eq $TRUE)

14.                    write-host "Feature "  $feature.DefinitionId " has been removed."

17.                        catch {
18.                            write-host "An error occured while removing feature:"  $feature.DefinitionId
