Microsoft 365 Migration & Enablement Services
From new tenant setup to complex global migrations — every engagement is engineered to protect your data, your users, and your timeline.
A secure foundation before the first user migrates.
A poorly configured tenant creates problems that compound over time — governance gaps, security exposures, and structural debt that slows every future migration. Summit builds your Microsoft 365 environment the right way from the start, so you never have to go back and fix what should have been done correctly the first time.
Start with SetupWhat's included
- New tenant provisioning & baseline configuration
- SharePoint architecture & landing zone design
- Security & compliance baseline — Conditional Access, DLP, MFA
- OneDrive policy configuration
- Exchange Online setup & mail flow configuration
- Migration-ready tenant assessment
The migration type most generalist firms avoid. Summit specializes in it.
Tenant-to-tenant migrations are the most technically complex engagements in the M365 ecosystem — two tenants, two identity systems, two sets of data, one deadline. When an acquisition closes, the pressure is immediate. Summit has the methodology, the tooling experience, and the track record to execute these engagements without surprises.
Plan a T2T EngagementWhat's included
- Tenant-to-Tenant migration — M&A, divestiture, consolidation
- Tenant coexistence & GAL sync setup
- Directory integrity & identity mapping
- Governance preservation across the merge
- Wave-based migration with delta syncs
- Post-migration tenant cleanup
Leaving Box, Dropbox, Google, or Egnyte behind — cleanly.
Cloud-to-cloud migrations look simple until metadata disappears, permissions collapse, and folder structures arrive as a flat pile. Summit maps your source environment before a single file moves, preserves what matters, and delivers a SharePoint and OneDrive environment that users can actually navigate on day one.
Discuss a Cloud MigrationWhat's included
- Box → SharePoint / OneDrive
- Dropbox → SharePoint / OneDrive
- Google Drive → SharePoint / OneDrive
- Google Workspace → M365 full suite
- Egnyte → SharePoint / OneDrive
- Metadata & permissions preservation
Mail flow doesn't stop. Neither do we.
Email migrations have a low tolerance for error — disrupted mail flow affects every person in the organization immediately. Summit executes Exchange Online migrations with careful cutover planning, DNS coordination, and post-migration validation to ensure nothing is lost and nothing stops working.

Stalled migration. Blown timeline. We've seen it before.
Not every migration goes as planned. Tooling fails, scope expands, timelines slip, and suddenly the project is in trouble. Summit has stepped into troubled engagements at every stage — assessed what went wrong, stabilized the environment, and finished the job. If your migration is off the rails, there is a path forward.
Stabilize Your ProjectWhat's included
- Stalled migration recovery
- Data integrity assessment & remediation
- Timeline & scope recovery planning
- Third-party tool troubleshooting
- Root cause analysis
- Re-engagement planning & execution
