Microsoft 365 Migration
Migrate from Google Workspace, on-prem Exchange, or a legacy M365 tenant — without an inbox going dark on Monday morning.
Microsoft 365 migrations look simple in the sales demo. In practice they go wrong at mailbox cutover, shared-calendar handoff, SharePoint permission mapping, OneDrive sync conflicts, and the 2 a.m. "wait, my signatures are gone" crisis. We run the whole move: discovery, licensing, tenant setup, mailbox and data migration, MFA and conditional access, client-side reconfiguration, and a sit-by-your-people cutover week. Houston-based engineers, on-site when the project calls for it.
What’s included
The specifics.
- ✓Source discovery (Google Workspace, on-prem Exchange, IMAP, legacy M365 tenant) and inventory of mailboxes, shared mailboxes, distribution groups, calendars, and delegations
- ✓License plan (Business Basic / Standard / Premium vs. Enterprise E3 / E5 + Copilot add-on) tuned to your compliance posture and budget
- ✓Tenant provisioning, domain verification, DNS and SPF / DKIM / DMARC alignment — without breaking your live mail flow
- ✓Mailbox migration with PST backfill, shared-mailbox and resource-calendar handoff, and public-folder conversion
- ✓SharePoint / OneDrive data migration with permission mapping (not the default "everybody has access" dump)
- ✓Microsoft Entra ID (Azure AD) identity, MFA enforcement, conditional access policies, privileged-role protection
- ✓Outlook profile rebuild, signature handling, calendar re-sharing, and client-side desktop/mobile reconfiguration
- ✓Cutover week on-site — our engineers sit with your people the day mail routing flips
- ✓30-day post-cutover support and a clean handover to your ongoing Managed IT
Who needs this
Businesses moving off Google Workspace, on-prem Exchange, or a hosted-Exchange reseller. Companies consolidating multiple M365 tenants after M&A. Practices that adopted M365 Basic years ago and now need Copilot, Purview, or compliance-aligned configuration. Firms preparing for a SOC 2, HIPAA, or CMMC audit who need the M365 side operationalized.
FAQ
Microsoft 365 Migration — common questions.
How long does a typical M365 migration take?
Small-to-mid practice (up to ~50 mailboxes): 3–5 weeks end-to-end, with the actual mail-routing cutover typically done over a weekend. Larger or multi-tenant migrations: 6–12 weeks. The number that matters isn't the tech — it's how quickly we can get discovery access and stakeholder time for shared-resource decisions.
Will my email go down during the migration?
No. We run coexistence during the migration window (mail flows through both systems) and the cutover itself is planned — usually a Friday evening after-hours with Monday morning ready. We've never had a client lose a business day of email.
What happens to our existing email archives and PST files?
They're part of the migration. We inventory PSTs on user machines and network shares up front, get them into the new tenant with proper retention applied, and give you a single searchable archive instead of a pile of PST files nobody can find.
Can you migrate us from Google Workspace?
Yes — Google Workspace → M365 is one of the migrations we run most often. Gmail, Google Drive, shared drives, calendar, contacts — all handled. The tricky part is usually Google Groups → M365 distribution groups / shared mailboxes; we map that explicitly as part of discovery.
Do we need E5 to migrate?
No — start where the license math works, upgrade per-user when the features justify it. For regulated clients (healthcare, legal, CPA) E3 + Purview + Copilot often beats E5 on cost. We do the license modeling as part of the plan.
What does this cost?
Migration work is scoped in writing after a paid 1-week discovery — no open-ended hourly. Houston-metro practices typically see migrations in the mid-four to low-five figures depending on mailbox count and complexity. Licensing is pass-through at Microsoft's published price.
