What is the best way to duplicate maps?

I am having a hard time properly duplicating maps in the Unreal Editor to test variations of it.

I tried using the Migrate Asset action and migrating my map to a Developers Collections folder. The problem when I do that is that it duplicates all the referenced assets in that folder but the new migrated map doesn’t actually reference the duplicated assets. For example, the sublevels in the duplicated map are still the original ones. If I switch the sublevels to the duplicated ones, then I get a black screen when running the game in editor. I thought this way of doing things would be the desired way since I use the editor migrate action to create a test map in the developers folder.

If I simply duplicate the map and its sublevels, I have the same problem where I have to manually change the duplicated map to reference the duplicated sublevels. And I still end up with a black screen when running the game in editor.

Is there a simple way to copy a map and have its sublevels and have them reference existing blueprints?

Thanks.
