Question

Has anyone done a Box to O365 migration?  Looking for some ideas/thoughts.

Answer

I was not part of the infrastructure team that handled the migration, but our org moved ~100k accounts from Box to OneDrive/O365 last year. Overall it was a relatively uneventful transition for most end users, except for those who had built integrations using Box's uploader widgets and other workflows that could not be directly (or easily) reproduced in O365.

Answer

I have done this at a previous company. We used a tool called SkySync to first sync our on-prem file server to Box and then cut over to Box completely. Next, as part of our BCP/DR plan, we then synced Box to OneDrive using SkySync to accommodate the sync. At the time, we did have to reset permissions once the files landed on Box, but it was a good exercise to go through as we caught a lot of folders that shouldn't be widely shared. This was a few years ago so I am assuming the SkySync tool has progressed  on features since then. Hope that helps.
