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.

Why this matters

Surface the risks before migration work begins

Migration risk often sits in ownership, permissions, identity, workflows, integrations, and business validation. We bring those issues into the plan before they become cutover problems.

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.

Representative situations

A fit for environments with real dependencies

The work is most valuable when the move includes technical complexity, business-critical processes, or governance decisions that cannot be left until the end.
  • Microsoft 365
  • SharePoint Online
  • Teams
  • OneDrive
  • Exchange Online
  • Power Platform
  • Azure
  • Entra ID

Where we are typically brought in

Complexity that requires senior migration judgment

  • Tenant, SharePoint, Teams, OneDrive, Exchange, and Power Platform moves with real business validation requirements.
  • Migration programs where permissions, ownership, workflows, forms, integrations, or compliance constraints create risk.
  • Organizations that need senior Microsoft migration judgment, not only tool operation.

Before and after

Move from uncertain scope to a controlled plan

The goal is not simply to move data. It is to create a target state, sequence the work, and leave the environment easier to operate.

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.

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.

Business case

Give leadership a decision-ready migration path

The technical plan should also support budget, procurement, operating continuity, and stakeholder communication.
  • Reduce unsupported platform and operational continuity risk.
  • Protect business processes during cutover and modernization.
  • Create a defensible migration roadmap for leadership, budget, and procurement conversations.
  • Improve Microsoft 365 adoption by landing users in a cleaner, governed target state.

Delivery approach

A practical path from discovery through handoff

Each engagement is adapted to the source systems, target environment, timeline, risk tolerance, and capacity of the internal team.
01

Inventory and classify

Assess ownership, volume, sharing, active use, path issues, and retention needs.

02

Design destinations

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

03

Migrate in waves

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

04

Stabilize

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

Deliverables

Artifacts your team can use after the engagement

The output is structured for administrators, project managers, business owners, and leadership.
  • Discovery report
  • Source-to-target mapping
  • External sharing review
  • Migration wave plan
  • Validation checklist
  • Governance backlog

Questions

Frequently asked questions

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.
