If you want to go down the renaming route, you can use Find and Replace by limiting the scope to the path, then changing the path to the new version you need:
Tree view - Spine User Guide: Find and replace
If your use case happens to have no folders before the path that you may use in the Find field, you can check First occurrence and Regular expression
then type in the Find field: (.*) and in the Replace field: newfolder/$1 where instead of "newfolder" you can type the new path to use.
