How could I transfer leaderstats data from old leaderstats to a new leaderstats script?

So, I need to transfer my leaderstats from the old one because I need to add abbreviations, but the problem is I would need to make a new leaderstats because it needs 1 folder, and I need 2 folders. But if I do a 1 folder leaderstats, it would need a datareset.

No, it totally wouldn't! Just add an abbreviations value to the leaderstats Folder and save it in your Datastore.
