File Share & SharePoint Migration to Microsoft 365

Move your files to SharePoint Online, OneDrive and Teams without losing structure, permissions or a working day.

We migrate content from file servers, older SharePoint versions and cloud drives such as Google Drive, Box and Dropbox into Microsoft 365. Every migration starts with an inventory and clean-up, maps structure and permissions to a modern design, pilots first, then runs bulk and incremental passes with validation, so users switch over with everything where they expect it.

Why migrations go wrong

“We copied everything, and now nobody can find anything.”

A lift-and-shift copies 15 years of clutter and deep folder paths into the cloud.

“People lost access on Monday morning.”

Permissions and identities were not mapped before cut-over.

“Our SharePoint 2016 server is out of support.”

SharePoint Server 2016 and 2019 reached end of support in July 2026, so the server no longer gets security updates.

What we deliver

Migration paths we handle

Planned, piloted and validated, using Microsoft’s supported migration tools.

File server & NAS to SharePoint

Network shares moved into SharePoint libraries and Teams, with structure redesigned where needed.

SharePoint Server to SharePoint Online

Sites, lists, libraries and permissions from SharePoint 2013, 2016 and 2019 moved to the cloud.

Google Drive, Box, Dropbox & Egnyte

Cloud drives moved into OneDrive and SharePoint with permissions and identity mapping.

OneDrive & Known Folder Move

Personal files and desktops synced to OneDrive for every user.

Workflow & customisation review

Old workflows, InfoPath forms and add-ins assessed and rebuilt with Power Automate, Power Apps or SPFx.

Validation & cut-over

Counts, permissions and spot checks validated before users switch, with incremental syncs until cut-over.

What’s new in 2026

Migration tools have changed

Microsoft’s migration stack is more capable, and some older options are gone. What we use and plan around:

  • Migration Manager now covers file shares plus Google Drive, Box, Dropbox and Egnyte; the separate Mover tool is retired
  • SharePoint Migration Tool (SPMT) for on-premises SharePoint sites and lists
  • Incremental runs (delta or full) keep the destination current until the cut-over weekend
  • End of support: SharePoint Server 2016/2019 support ended 14 July 2026; the options are SharePoint Online or SharePoint Server Subscription Edition

Tool limits apply: for example, maximum file sizes, and folder-level versus file-level permissions for some cloud sources. We plan around them in the assessment.

FAQ

Migration questions, answered

Plain answers to what business owners ask before they start.

Ask us a question
How long does a file migration take?

It depends on volume, file count, network and clean-up. Small shares can move in days; larger estates are migrated in waves over several weeks with incremental syncs.

Will permissions be kept?

We map users and groups first and migrate permissions where the tool supports it, simplifying them to a modern model where possible.

Can people keep working during migration?

Yes. Bulk copies run in the background, incremental passes keep content current, and users switch on a planned cut-over date.

Our SharePoint 2016 server is out of support. What are our options?

Move to SharePoint Online in Microsoft 365, or upgrade to SharePoint Server Subscription Edition if you must stay on-premises. We help you choose and migrate.

What happens to old workflows and InfoPath forms?

They don’t migrate as-is. We rebuild the ones still needed with Power Automate and Power Apps, and retire the rest.

Can you migrate from Google Drive or Dropbox?

Yes. Microsoft’s Migration Manager supports Google Drive, Box, Dropbox and Egnyte; we handle identity mapping, scanning and validation.
