Wanted to update you on a great feature that is being rolled out in O365, soon you will be able to move a file between services with full fidelity.
Moving the file is as easy as a few choices in the ribbon as you can see in this article. This feature has most likely already hit your first release tenant or will be in the next month with the rest of the other tenants in the next 3 months.
Some of the reasons you will want to use this feature:
Clean-up: For whatever reason you have a file that has been misplaced be that a mistake in a migration, or a user created the file in the wrong place
Consolidation/Migration: Site architecture changes, departments or teams move. Whatever the reason you can now use this to move documents between those locations
