Google Workspace to Microsoft 365 Migration in Winchester
Moving Winchester organisations from Google Workspace to Microsoft 365, where the sharing links people have already sent out are what break. Every Drive link in an email, a contract or a supplier's records points at a file that will no longer be there — and nobody has a list of where those links went.
Why this comes up
The problem
Clients and suppliers hold Drive links to documents that will stop resolving on cutover day.
What you get
What we deliver
- Externally shared files identified, since these are where the breakage lands
- Mail, calendar and contacts migrated with a tested cutover for each
- Drive content moved to SharePoint and OneDrive with ownership decided
- Document conversion checked, because formatting does not always survive
- Sharing permissions rebuilt rather than assumed to transfer
- Shared mailboxes, groups and aliases reproduced so nothing goes undelivered

Google Workspace to Microsoft 365 Migration in Winchester — common questions
- Why do shared links matter so much?
- Because they exist outside your control. A Drive link sent to a client two years ago still works today and will not after the move, so identifying externally shared files and deciding what to do about them is the step that prevents awkward conversations.
- Do documents convert cleanly?
- Mostly, with exceptions worth checking. Google Docs become Word documents and formatting is usually preserved, but complex spreadsheets with scripts, add-ons or unusual formulas need testing individually rather than trusting a bulk conversion.
- What is the risk with email?
- Losing messages in the switchover window. Mail arriving while records are being changed can land in either system, so a migration with a tested cutover and a coexistence period is the difference between a smooth Monday and a lost morning of correspondence.
- What is most often forgotten?
- Shared mailboxes, distribution groups and aliases. They are invisible until something addressed to them silently fails to arrive, and because nobody owns them personally, their absence is often noticed weeks later by whoever was expecting a reply that never came.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Winchester and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Winchester businesses do you usually work with?
- Client portals and document systems for legal and financial practices, with confidentiality driving the design. Beyond that we work across Professional Services, Higher Education, Tourism & Heritage, Retail and Healthcare.
- Do you cover the areas around Winchester?
- Yes — we work throughout South East, including Southampton, Salisbury, Portsmouth. Winchester is an urban area of roughly 50,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
