Two questions related to Files & Enhanced Notes for Lightning:

1. For anyone who has moved to Lightning and migrated all Attachments to Files - what benefits have you seen? I'm not sure I can see why I would have my team spend time migrating if Notes & Attachments related list still works in Lightning.

2. When running the magic mover app to migrate, are we essentially doubling the storage space we use if we now have the files in two places? If so, any considerations?
