Data Migration

How to plan a move from a Windows file share into SharePoint Online without losing a weekend or the trust of your staff — what discovery must measure before anything moves, how to decide what migrates, what gets archived and what gets deleted, how to design sites, libraries and metadata that still make sense in five years, how to translate NTFS permissions into Microsoft 365 groups, a realistic twelve-week plan from scan to decommissioning, the tooling and throughput limits that shape it, the mistakes that force a rollback, and the questions that expose the difference between two very different quotes.

What a move into SharePoint Online really costs a UK organisation in 2026 — the six components behind every quote, professional-services price bands from under twenty-five users to three hundred and above, the hidden extras that inflate the bill, what migration tooling adds, a realistic week-by-week timeline from discovery to decommissioning, the mistakes that double a project, and the five questions that expose the difference between two very different quotes.
