Architecture before movement
Domains, identities, permissions and security baselines are designed before data lands.
Move to Microsoft 365 without opening the side door.
A migration is a security event. NeoDefender moves email, files and collaboration into Microsoft 365 with the new tenant hardened before users depend on it.
Three principles: architecture, precision and resilience.
We do not just move mailboxes. We rebuild the security foundation around the Microsoft ecosystem you are adopting.
Controlled transition
Pilot batches, clear windows and coexistence planning reduce user disruption.
Hardening from day one
Defender, MFA and access policies are active before the tenant becomes business-critical.
The cutover is only one step. The risk window starts earlier.
The project is phased so users know what is changing, admins know who owns each step, and the new tenant is defensible before go-live.
01
Discovery
Source mail, domains, identities, devices, data volume and risk are mapped before any cutover.
02
Tenant hardening
Conditional Access, MFA, Defender baselines and admin controls are live before data arrives.
03
Pilot migration
A controlled user group validates mail flow, permissions, mobile access and support runbooks.
04
Cutover
Mailboxes, data and DNS move in planned windows with rollback paths and user communication.
05
Hypercare
Thirty days of stabilization, monitoring and user support after the move.
Migration calculator for the first serious conversation.
It is not a quote. It is a working estimate that shows where effort usually lands: users, data volume, source platform and whether Teams also needs to move.
Source platform
Complex permissionsSpaces with custom sharing rules, granular access controls, or non-standard inheritance. If unsure, pick the closest range.

This is an estimate based on standard scope. Final price may vary based on discovery findings (legacy customizations, third-party integrations, compliance requirements).
Teams Phone also lives in this migration.
If your migration includes voice, Teams Phone can replace your existing phone system with calling, queues, auto attendants, and number porting - all inside the same Microsoft environment. Plan voice as part of the same project, not as a separate program.
Plan voice migrationQuestions worth answering before the first call.
What is NeoDefender's Microsoft 365 migration service?
It is an end-to-end migration service for email and related collaboration services, with a security baseline implemented before users begin working in the new tenant.
What benefits does a company get by migrating to Microsoft 365?
You consolidate email, collaboration, storage and productivity in one ecosystem: Exchange Online, OneDrive, SharePoint, Teams and the Office apps.
How long does a migration take?
It depends on user count, data volume and the complexity of the current environment. We phase the work so the change feels like an upgrade, not an interruption.
How does NeoDefender reduce migration surprises?
We review domains, security, current configuration and data flow before moving mailboxes, reducing the risk of data loss, rejected mail and downtime.
Why use specialists instead of doing it internally?
A specialist team reduces rework, shortens risk windows and makes sure productivity and security are handled together from the first login.
