Hi
@si26! On the newer versions of Umbraco you are able to view the relations on the document type itself under the Info tab. For Umbraco 8 and below, you could make use of the package that inspired the actual integration for U9+ called Nexu!

This will however only show the relations, not actually allow you to change them, so if you are talking about changing 200 pages, doing so the database route may still be a valid option
