Another day, another opportunity to spackle the walls of SharePoint where there’s a hole. Wouldn’t it be great if you could go somewhere in the SharePoint Admin Center to see all the places you’ve used a particular Web Part in pages? Well, you can’t, so PowerShell. PnP.PowerShell, in fact.

You may be considering migrating your videos from Stream Classic to Stream in SharePoint. After all, it’s got to happen sooner or later, and the migration tool is now available for everyone. At Sympraxis, we’ve started to help our clients with these migrations, usually in the context of other work.

One thing you’re likely to want to know is where you have used the Stream (Classic) Web Part in your pages. Depending on how you do the migration, it is likely going to be a good idea to visit many of those pages to either switch to the Document Library Web Part or at least validate the Stream (Classic) Web Parts are working.

Just as I did when I upgraded from the PnP Modern Search Web Parts v3 to v4 (See: Upgrading the PnP Modern Search Web Parts from v3 to v4: Where are they?), I turned to PowerShell. I grabbed that same script and buffed it up a bit to find the Stream (Classic) Web Parts this time.

I took a bit of a different approach with this iteration, though. Rather than using search to find the pages with the Web Parts (I found it was missing some), I switched to using Get-PnPPageComponent | PnP PowerShell. This allows me to get the Web Parts (aka Page Components) in a page directly.

The script below is what I used. I’ve included some comments to indicate where you might choose to do things a bit differently, depending on your environment and your goals. I’m just outputting the info to the console, as the tenant where I’m working isn’t that dense. You may choose to output to a CSV file or something else.
