A smooth migration
CitNOW's data was migrated from the old setup into a SharePoint intranet and document management system so dispersed teams can find and co-author work, and the migration went smoothly.
SharePoint migration
SharePoint migrations, planned properly.
We migrate organisations to SharePoint Online from on-premise SharePoint, file shares, other tenants, Lotus Notes and Google Workspace, with minimal downtime. Each migration runs as a structured project, with an audit, a target architecture, a pilot and validation before go-live.

How we work
How a SharePoint migration runs.
01
Discovery
We audit your source environment with automated scanning and manual review, covering content volume, site structure, customisations, permissions and content that no longer needs to move.
02
Design
The target information architecture in SharePoint Online: hub sites, libraries, metadata and permissions, with every source location mapped to a destination and a remediation plan for custom solutions.
03
Build
A pilot migration of a representative sample, validated by your key users, followed by the full migration in scheduled batches with validation checks after each one.
04
Train
Training for your people on the new environment, so they know where things are and how to work in modern SharePoint.
05
Go live
We check document counts, metadata, permissions, broken links and search results, then support your people through go-live.

FAQ
Frequently asked questions.
How long does a SharePoint migration take?
As a guide, 4 to 6 weeks for organisations under 500 users with straightforward content, 6 to 10 weeks for 500 to 5,000 users with some customisations, and 10 to 16 weeks for 5,000+ users, sometimes phased by business unit.
Which migration tools do you use?
Microsoft SPMT for straightforward migrations, ShareGate for complex SharePoint Server moves with granular permissions and large volumes, and custom PowerShell or Graph API scripting for non-SharePoint sources. We recommend the tool, or combination, during scoping.
What happens to our custom solutions?
Farm and sandbox solutions do not work in SharePoint Online. We audit each one and recommend replacing it with native features, rebuilding it in SPFx or converting it to Power Platform.
Will our users be disrupted?
The full migration runs in scheduled batches, typically over evenings and weekends, with validation after each batch and rollback procedures in place.
