You can continue using the legacy app.
If I add new maps in the same native pattern will I be able to display them in the modern interface? I don't know if I expressed myself well
We do support custom maps in the modern app. The URL format should be the same.
I don't know if I understand but the maps displayed in the modern interface have a link that points to the same maps in the legacy interface?
if so where can i find this link?
Some maps are the same and some are different:

I use version 4.7 with some custom maps. I would like to know if it is possible to keep them if you upgrade to 5.2. Are the js in web/app/view/map?
