How long does an email migration take?

Timeline depends on the number of mailboxes and total data volume. A typical small business (10-50 mailboxes) takes 1-2 weeks including planning, testing, migration, and validation. Larger migrations may take 3-4 weeks. We provide a detailed timeline before starting.

Will I lose any emails during migration?

No. Our migration process preserves all emails, contacts, calendars, and folder structures. We use staged migration with verification at each step, and we keep your source system active until the migration is fully validated.

Can you migrate from Google Workspace to Microsoft 365?

Yes. We regularly migrate businesses from Google Workspace (Gmail) to Microsoft 365, preserving all email, contacts, calendars, and Drive files. We also handle the DNS cutover and user training on the new platform.

Do you provide training after the migration?

Yes. We provide user training covering the new platform's key features including email, calendar, contacts, and collaboration tools. We also offer a dedicated support period after migration to quickly resolve any questions or issues.

Quick IT Tips

Practical advice you can use right now — whether you work with us or not.

•Do not cut over DNS on a Friday. If something unexpected comes up, you want your full team available to resolve it quickly.
•Set up your SPF, DKIM, and DMARC records before the cutover — not after. Missing email authentication is one of the most common post-migration deliverability problems.
•Run a small pilot migration with a few test mailboxes before touching production. It surfaces issues when the stakes are low.
•Tell your team about the migration a week ahead. A five-minute heads-up prevents a hundred support calls on cutover day.
•Keep your old email environment running in read-only mode for two to four weeks after migration. It is an inexpensive safety net if anything was missed.
