Provide an upgrade path from Win 7x/8x Libraries to the local Onedrive and then to online Onedrive.
We need an upgrade path to make sure we know the following:
How to move files in the Libraries to local Onedrive (maybe make it it's own library)
Determine which files in the local Onedrive need to be sync'd with the online Onedrive.
Determine which files in the local Onedrive should be backed up to an NAS.
I feel your implementation of the Win 10 local Onedrive isn't very clear and frankly confusing.
