Folder Structure Preservation

Existing folder hierarchies replicated exactly in SharePoint and OneDrive. No files moved to unexpected locations. Users find their content where they expect it, reducing adoption friction.

Permissions Audit and Mapping

Every permission on every folder audited before migration. Permissions mapped to equivalent Microsoft 365 groups and roles. Overly permissive access identified and corrected during migration.

Post-Migration Validation

File counts and sizes verified against source after migration. Random sample checks performed on migrated content. Any discrepancies resolved before old file server is decommissioned.

How We Work

A six-stage process built around zero surprises.

01

File Environment Discovery

We scan your existing file environment: total data volume, folder depth, file types, age profiles, and permission structures. A migration report is produced identifying any issues before migration begins.

02

SharePoint Architecture Design

SharePoint Online site structure designed to match your business. Document libraries created, metadata columns configured, and permission groups established before any data moves.

03

Permissions Mapping

NTFS or Google Drive permissions mapped to Microsoft 365 security groups. Users and groups created or synchronised from Active Directory. Permissions validated against source before migration runs.

04

Pre-Migration Sync

Files pre-synced to SharePoint and OneDrive in the background while your existing file server remains live. Delta syncs run continuously to keep the destination current.

05

Cutover and Validation

Final sync completed. File counts and sizes verified. Users redirected to SharePoint and OneDrive. Old file server access removed. Any missing files identified and resolved within the same day.

06

User Orientation and Decommission

Users shown how to access their files in SharePoint and OneDrive. OneDrive sync client configured on all devices. Old file server decommissioned once validation is complete.

Real Results

File migrations delivered across the UK.

File Server Decommission

A Leeds engineering firm had 2TB of data spread across three ageing Windows file servers. The servers were approaching end of life and the business wanted to move to cloud storage to reduce infrastructure costs.

All 2TB migrated to SharePoint Online and OneDrive over three weeks. Folder structures preserved exactly. NTFS permissions mapped to Microsoft 365 groups. File servers decommissioned on schedule. Annual infrastructure saving of over 12,000 pounds.

Google Drive Exit

A Bristol marketing agency was leaving Google Workspace for Microsoft 365. They had 800GB of shared drive content and 45 personal Google Drive accounts, all containing Google Docs and Sheets.

All shared drive content migrated to SharePoint Online. Personal drives moved to OneDrive. Google Docs converted to Word and Excel format. Sharing permissions remapped. Agency fully operational on Microsoft 365 within two weeks.

NAS to OneDrive Migration

A Cardiff accountancy practice had a NAS device used for personal file storage by 30 staff. The device was unreliable and the practice wanted to move to OneDrive for automatic backup and anywhere access.

All personal folders migrated from NAS to OneDrive for Business. Known Folder Move configured to keep Desktop, Documents, and Pictures in sync. NAS retired. Staff could access files from home and mobile immediately.
