Microsoft 365 migration FAQs — London
Q.How long does a Microsoft 365 migration take?
A typical Microsoft 365 email migration for a 20–50 user business takes 1–2 weeks from start to finish, including planning, test migration, and cutover. Larger or more complex migrations may take 3–6 weeks. Coreitech provides a detailed timeline before any work begins.
Q.Will there be email downtime during a Microsoft 365 migration?
No. Coreitech designs all Microsoft 365 migrations to be zero-downtime. We use DNS cutover techniques and parallel mail flow to ensure your email continues to work throughout the migration.
Q.Can you migrate from Google Workspace to Microsoft 365?
Yes. We perform full Google Workspace to Microsoft 365 migrations — including Gmail to Exchange Online, Google Drive to OneDrive/SharePoint, Google Calendar to Outlook Calendar, and Contacts. All data is migrated with full fidelity.
Q.What happens to our data during the Microsoft 365 migration?
All data is migrated securely and encrypted in transit. We run a pre-migration audit, test migration on a subset of accounts, then full migration. We keep source data intact throughout and only decommission the old platform after you've validated the migration.
Q.Do you provide post-migration support after a Microsoft 365 migration?
Yes. All Microsoft 365 migrations include a post-migration support period — typically 2–4 weeks — during which our team monitors the new environment and resolves any issues at no additional cost. Ongoing management is then handled through our managed IT support service.
