File Server to OneDrive and SharePoint Migration Plan

Migrate a 2 TB on-premise file share to OneDrive and SharePoint without losing permissions.

The Scenario

A SA professional services firm of 60 staff has a 2 TB on-premise file share with deeply nested folders, NTFS permissions, and a directory structure that nobody fully understands. The CIO has approved a move to OneDrive (personal) and SharePoint (team) inside Microsoft 365.

The Brief

Produce a complete migration plan: discovery, mapping, tooling choice, cutover, and post-migration support. The plan must address the permission translation problem and the inevitable user resistance.

Deliverables

  • A discovery plan covering: data classification, owner identification, permission audit, and "rot" identification (stale folders to leave behind)
  • A mapping document showing how on-premise folders map to OneDrive personal libraries versus SharePoint team sites, and how NTFS permissions translate to M365 sharing
  • A tooling recommendation comparing native (Migration Manager) versus third-party (ShareGate, Mover) options with cost and complexity trade-offs
  • A 30-60-90 day adoption plan covering training, support, and the timeline to decommission the old file server

Submission Guidance

The technical migration is the easy part. The hard part is permission translation, which folders go where, and getting users to stop dragging files back to the old server. Show that you understand the change management dimension.
