This post is the second of a series explaining how to audit your SharePoint farm.

Extracting Customizations from the Farm

When auditing the customizations of your SharePoint farm, the first step is to retrieve all of them in their currently deployed versions.

This can be achieved by some PowerShell code executed on one of the farms servers.

Log in to one of your server on your SharePoint farm (you will require farm administrator permissions)
Create a local folder to store the customizations.
Open a SharePoint Management Shell (PowerShell) window and browse to that new folder.

Extract all WSPs and/or Apps from SharePoint by running the following PowerShell scripts

Full trust farm solutions

$ftcPath = "filepath to store the full trust farm solutions"
(Get-SPFarm).Solutions | % {
        $_.SolutionFile.SaveAs($ftcPath + "\" + $_.Name)
}

Sandboxed solutions (from a single site)

$sbsPath = "filepath to store the sandboxed solutions"
$site = Get-SPSite "http://<url to site>"
$listTemplate = [Microsoft.SharePoint.SPListTemplateType]::SolutionCatalog
$solGallery = $_.GetCatalog($listTemplate)
$solGallery.Items | % {
    [System.IO.FileStream]$outStream = New-Object System.IO.FileStream(($sbsPath+"\"+$_.File.Name), [System.IO.FileMode]::Create);
    $fileData = $_.File.OpenBinary();
    $outStream.Write($fileData, 0, $fileData.Length);
    $outStream.Close();
}

SharePoint Apps (from a single web)

$appPath = "filepath to store the apps"
$instances = Get-SPAppInstance -Web "http://<url to web>"
foreach ($instance in $instances) {
    $filename = [RegEx]::Replace($instance.Title, "[{0}]" -f ([RegEx]::Escape([String][System.IO.Path]::GetInvalidFileNameChars())), '')+".app"
    Export-SPAppPackage -App $instance.App -Path ($webPath + "\"+ $filename)
}

Copy the folder with your customizations to a network share, which is accessible from where you run SPCAF

I want them all!

The code above just illustrates how to get solutions and apps from a single instance of a site or web.

To extract all code customizations from the farm you can use the following complete script. It retrieves them from all sites and webs which are accessible by the account executing the script.

It creates a folder named after the current date, subfolders for full trust solutions, sandboxed solutions and apps as well as subfolders for each site or web that contains a customisation.

During execution it logs the processed sites, solutions and apps.

Great, what now?

Now that you have extracted all code customizations you might wonder what to do with them.
