Cloud Storage
Migration

Move your organisation off Google Drive, Dropbox, or Box and onto Microsoft OneDrive and SharePoint Online — with permissions mapped, version history preserved, and shared drives intact.

Overview

What this migration involves

Cloud storage migrations involve more than copying files. Permissions, folder structures, sharing configurations, version histories, and team drive memberships all need to translate correctly to the target platform.

CloudyNex maps source storage structures to the correct Microsoft 365 destinations: shared team content to SharePoint Online, personal files to OneDrive, with permissions remapped to the equivalent Microsoft 365 groups and individuals. Moving off an on-premises file server? See our file server to SharePoint & OneDrive guide.

What we migrate
  • All files and folder structures preserved
  • Permission mappings and sharing configurations
  • Version history where supported by source platform
  • Shared drive and team folder contents
  • External sharing links documented and remapped where possible

Business Challenges

What makes this migration complex

01
Permission translation

Google Drive, Dropbox, and Box each have different permission models. These must be carefully translated to SharePoint and OneDrive permissions without creating access gaps or over-exposure.

02
File format compatibility

Google Docs, Sheets, and Slides must be converted to Microsoft Office formats. Most convert cleanly; complex documents may need post-migration review for formatting accuracy.

03
Volume and performance

Large storage environments require careful batch management to complete within acceptable timeframes without overwhelming source or destination APIs.

Our Process

How we run the migration

01 — Audit
Storage audit
Full audit of source storage — file count, volumes, folder structures, permissions, and external sharing.
02 — Planning
Destination mapping
Source folder structures mapped to SharePoint sites and OneDrive accounts. Permission translation documented.
03 — Pilot
Pilot migration
Selected team folders migrated to validate permission mapping and file conversion accuracy.
04 — Pre-stage
Background sync
All file content synced in the background before cutover to minimise the live migration window.
05 — Cutover
Source decommission
Final delta sync, source platform decommissioned, OneDrive and SharePoint activated as primary storage.
06 — Hypercare
Post-migration
7-day support for access issues, missing files, and permission corrections. Full integrity report provided.

FAQ

Frequently asked questions

Existing sharing links from the source platform stop working when it is decommissioned. New sharing links can be created in SharePoint and OneDrive. Critical shared links are documented during discovery.
Version history migration depends on the source platform and tooling. We migrate as much version history as the platform APIs allow. Current versions are always fully migrated.
Files shared externally are migrated. External sharing configurations are mapped where possible. All external sharing is documented during discovery so nothing is missed.
