Content platform migration

Box/Dropbox to SharePoint and OneDrive Migration

Box and Dropbox migrations require careful decisions about ownership, sharing, external access, folder structures, and user habits. We move content into SharePoint, Teams, and OneDrive without recreating file sprawl.

What this solves

  • Inventory users, teams, folders, ownership, external sharing, storage volume, stale content, and sensitive areas.
  • Map Box/Dropbox structures to SharePoint sites, Teams, OneDrive, libraries, metadata, and security groups.
  • Run pilot and production waves with permission validation, communications, and post-migration cleanup.

Why this matters

Migration risk usually hides in ownership, permissions, identity, workflows, integrations, and business validation. Our role is to surface those risks early, design the Microsoft target state, and guide the move with clear controls.

Cleaner architecture

Decide what belongs in SharePoint, Teams, OneDrive, archive, or separate repositories before moving content.

External sharing control

Review external users and sharing links so the destination starts with safer access boundaries.

User-ready transition

Prepare users for SharePoint libraries, Teams files, OneDrive sync, and Microsoft 365 sharing behavior.

Before

What creates drag

  • Unclear scope, unknown owners, hidden dependencies, and migration waves based on incomplete inventory.
  • Technical migration success measured mostly by item counts, while business validation is left until late.
  • Legacy patterns copied into Microsoft 365 without improving governance, support, or ownership.

After

What good looks like

  • An inventory-backed plan with owners, dependencies, target architecture, validation gates, and remediation priorities.
  • Migration waves aligned to business processes, support readiness, communications, and go/no-go decisions.
  • A cleaner Microsoft operating model with governance, documentation, and post-migration support paths.

Map content to SharePoint, Teams, OneDrive, or archive, with group and permission strategy.

Migrate in waves

Pilot migrations, validate content and permissions, then run phased production migrations.

Stabilize

Support users, close access gaps, resolve sync issues, and document governance recommendations.

FAQs

Can external collaborators be preserved?

Some external access can be mapped, but it should be reviewed intentionally.

What goes to OneDrive versus SharePoint?

Personal work files usually go to OneDrive. Team-owned or process-owned content usually belongs in SharePoint or Teams.

Can this reduce storage costs?

Often yes. Discovery and cleanup can identify stale, duplicate, or archival content before migration.
