Problem with moving World Partiton map

I have a problem with moving and renaming a world partiton map. Let 's assume that my map is named old_map and inside \old folder. When I try to duplicate to a new folder under new name, everything works. However, I can’t delete old_map, because the new_map still have references to old external assets and HLODs. How can I completely migrate the old map to new one, without doing anything from scratch?

Hey there @Aravil01! Welcome back to the community! For the HLOD it seems another user dealt with this issue once before, however when it comes to the other external assets this may not work out.
