Export of Stream (Classic) Web Parts and pages that use them

Summary

Microsoft Stream (Classic) is scheduled to be retired. More information on this can be found at the following link.

Migration Overview - Stream (Classic) to Stream (on SharePoint)

In addition to migrating the videos, this retirement may also involve replacing Stream (Classic) Web Parts embedded within SharePoint pages.

This sample script helps you understand how many Stream (Classic) Web Parts are being used by your site by outputting a CSV file of the Stream (Classic) Web Parts and the pages that use them. The CSV file is created in the StreamClassicWebPartsReport folder in My Documents.

The following is a description of the CSV columns and a sample CSV output.

Column Name	Description
WebPartInstanceId	Instance Id of the Stream (Classic) Web Part.
SourceType	Type of source (BROWSE,VIDEO,CHANNEL) in the Stream (Classic) Web Part.
SourceVideoTitle	Title of the video (when SourceType is 'VIDEO') in the Stream (Classic) Web Part.
SourceURL	URL of the source in the Stream (Classic) Web Part.
PageTitle	Title of the page where Stream (Classic) Web Part is embedded.
PageURL	URL of the page where Stream (Classic) Web Part is embedded.
PageEditor	Editor of the page where Stream (Classic) Web Part is embedded.
