Is it possible to regenerate older parts of the map to get newer features? I’ve had this map since 2015. It’s originally from the Xbox one edition of Minecraft. Now I play on series x on the bedrock version.

As you can see the Xbox one edition portion of the map is the square in the center. I know that can’t be fixed but I was wondering if you’re somehow able to regenerate caves and water to get the better versions. Old Xbox one edition water just has sand and gravel with no plant life. The caves are all stone and dirt with no other rock types.

I would prefer to not load anymore new areas since my map has a lot of unused space in between cities.
