Ability to get a list of "Legacy Editor" pages in Confluence Space/s

Problem

Currently, there isn't a straight way to get a list of "Legacy Editor" pages in a Confluence Space.

Suggested Solution

To obtain the legacy editor pages list from the Space admin or enable CQL search with the legacy editor filter.

Why This Is Important

As we're moving towards New Editor in Confluence, it'll be useful to have a way to cross-check how many pages have been successfully converted to New Editor especially when the Legacy Editor page is converted using the bulk pages conversion feature.

This post - Detect if page been created by new or old editor through the REST API might help but still requires additional scripting for the list pages.

Workaround

There is no workaround at this stage.
