Removing all Enterprise SharePoint Features from a web application

Question

I am having a hard time determining which features to include in the removal process. Additionally, I am struggling to determine the order in which they should be removed. Could you please help me determine these two things? I included a list of suspect features on a typical site on this web app. In the list below, # means that I suspicious that the feature in question is enterprise, ## means that I have read that it is an enterprise feature, #### means that the feature is disabled if you disable enterprise features from the GUI. Once I have determined which features need to be disabled, I will need to use a script to loop through each web and site to disable these features. The script will likely look like this:

$siteFeatures = @("feature_ID1",`
    "feature_ID2",`
    "feature_IDetc")

$webFeatures = @("feature_ID1",`
        "feature_ID2",`
        "feature_IDetc")

Get-SPWebApplication "http://sp2010" | Get-SPSite -Limit ALL |
ForEach-Object {
    $thisSiteURL = $_.Url
    foreach($web in $_.AllWebs) {
        $thisWebURL = $_.Url
        foreach ($webFeature in $webFeatures) {
            if (Get-SPFeature -Web  $thisWebURL | Where {$_.ID -eq $webFeature})
                {
                    Disable-SPFeature $webFeature -Url $_.Url -WhatIf
                Write-Host "Feature " + $webFeature + " has been deactivated at :" $thisWebURL
                }
        }
    }
    foreach ($siteFeature in $siteFeatures) {
        if (Get-SPFeature -Site  $thisWebURL | Where {$_.ID -eq $siteFeature})
            {
                Disable-SPFeature $siteFeature -Url $_.Url -WhatIf
            Write-Host "Feature " + $siteFeature + " has been deactivated at :" $thisSiteURL
            }
    }
}

Answer 1

I would strongly advise against disabling manually features individually for 2 reasons:

1. You might never get them all - and even so - you might not get the right order (for this you really need to go through each feature, check dependencies in the Elements.xml and map that out - messy business!!!)
2. Even if you get them all and get them in proper order - you risk breaking functionality! It is enough for some user to use functionality which you are about to disable and content will be, SOMETIMES even iremediably lost!

Still, if you are going on that path a list of all 2010 is available at http://snahta.blogspot.ch/2010/06/sp2010-feature-ids.html or http://blogs.msdn.com/b/mcsnoiwb/archive/2010/01/07/features-and-their-guid-s-in-sp2010.aspx

Some of your list are:

• IPFSWebFeatures - InfoPath Forms Services (Hidden) - for sure Enteprise
• DataSourceLibrary (Hidden) - used in Team Sites - sounds like you'll breaking something ()
• Reporting - i believe it comes with as part of the Audit Reporting Feature (e.g. once i've been force to re-enable it to be able to check WOrkflow reports - also very basic - so i would avoid removing it!)

Answer 2

I added all the features in my list to my script and ran it mostly as-is (obviously swapping -whatif with -confirm:$false). It seems to have have worked.
