Microsoft 365
Migration

Move your entire organisation to Microsoft 365 — Exchange Online, SharePoint, Teams, and OneDrive — with a structured plan, minimal disruption, and complete data integrity.

Overview

What this migration involves

Microsoft 365 is an interconnected suite, not a single product. A thorough migration means moving email, files, collaboration tools, identity, and all integrations between them in the correct sequence.

CloudyNex approaches each workload systematically — assessing the source environment, planning each stream independently, and executing in a sequence that keeps your team operational throughout.

What we migrate
  • Exchange Online mailboxes, calendars, and contacts
  • SharePoint Online sites and document libraries
  • OneDrive for Business personal storage
  • Microsoft Teams channels, chats, and files
  • Distribution lists, shared mailboxes, and resource rooms
  • Security groups and Azure AD objects
  • Microsoft 365 licensing and admin configuration

Business Challenges

What makes this migration complex

01
Interdependent workloads

Exchange, SharePoint, Teams, and OneDrive share identities and permissions. Moving one without planning the others creates gaps that break user access.

02
Legacy configurations

On-premise setups accumulate years of custom rules, connectors, and undocumented configurations that must be mapped before migration begins.

03
User disruption risk

Email downtime or lost calendar data is immediately visible to every user. Cutover timing and communication planning must be precise.

Our Process

How we run the migration

01 — Discovery
Environment assessment
Audit of mailboxes, data volumes, configurations, third-party integrations, and licensing across all M365 workloads.
02 — Planning
Migration design
Batches, cutover schedule, rollback plan, and communication templates — all agreed in writing before anything moves.
03 — Pilot
Pilot migration
A representative group migrated first to validate the plan and surface edge cases in a controlled, low-risk way.
04 — Pre-stage
Data pre-staging
Initial data sync runs in the background, dramatically reducing the live migration window and user impact.
05 — Cutover
Migration execution
Final delta sync, MX record updates, and cutover — executed on schedule with live monitoring throughout.
06 — Hypercare
Post-migration
7-day priority support, integrity checks, user issue resolution, and documentation handoff.

FAQ

Frequently asked questions

Timeline depends on environment size and complexity. Organisations under 50 mailboxes typically complete in days. Larger enterprises may take several weeks. We provide a detailed timeline after the discovery phase.
Our pre-staging approach means the cutover window is very short — typically minutes, not hours. Cutovers are scheduled outside business hours with full rollback capability maintained.
All historical email, calendar entries, contacts, and folder structures are migrated. We run post-migration integrity checks to verify completeness before closing the project.
Every migration includes a documented rollback plan. The source environment is kept fully intact until migration is validated and signed off.
