We need to prioritize this. Rather than update a giant spreadsheet, I'm making a quick list and we'll go through directory together and update as needed.

Did the comparison yesterday and found a few pages that should have been redirected already, so added them to our redirect spreadsheet.

I also found a few more things we still have live and that we will need to either retire, redirect, or add to the migration list. Will share out with content members Friday/Monday and from those discussions, will be able to put in the new tickets.

Data shared out with content team this morning. I've groomed a couple tickets after that. We have a couple of conversations we need to have with business owners; those may result in a few more tickets.

The larger spreadsheet still needs some clean-up, but I've updated throughout. It revealed a few old things that needed redirecting, so those redirects were added to #4073.

We've developed this priority list of tickets: https://docs.google.com/document/d/1liKQT4XwW4z4evfJdMMWWdzuyeQVNGmijir4kUxfDhE/edit
