Migration

Ready to transform?

Complex challenges deserve expert solutions

Whether it's a full Microsoft 365 tenant cutover, a staged mailbox migration, or a workload-by-workload move — let's scope it together.

Overview

Zero data loss. Minimal downtime.

Migrations are judged on one thing: whether people could still work on Monday. We move mailboxes, files, applications and identities cleanly — tenant-to-tenant, on-premises to cloud and cloud-to-cloud — with the discovery work done up front so that cutover weekend holds no surprises.

Exchange Online

Cross-tenant mailbox migrations, coexistence, mail routing

Microsoft Teams

Channel structures, files, recordings, calling plan continuity

SharePoint & OneDrive

Document migration with preserved metadata, permissions, version history

Entra ID

Identity cutover, domain federation, Conditional Access re-configuration

Delivery methodology

Wave-basedPreferred

Phased user cohort migrations — each wave validates the process before broader rollout, reducing cutover risk.

Big-bang cutover

Single synchronised cutover event — suited to tight timelines, regulatory deadlines, or clean separation requirements.

Delivery phases

From discovery to cutover.

01

Discovery & Scoping

  • Tenant inventory & workload discovery
  • Data volume & complexity assessment
  • Licensing & dependency mapping
  • Risk identification & mitigation planning
02

Pre-Migration

  • Target tenant configuration & hardening
  • Coexistence setup (mail, Teams, calendar)
  • Pilot migration with representative users
  • User communication & training materials
03

Cutover

  • Synchronized cutover execution
  • DNS record updates & mail routing
  • Real-time monitoring & rollback capability
  • On-call support during hypercare period
04

Post-Migration

  • Source tenant workload decommission
  • Validation testing across all workloads
  • Documentation handover
  • Lessons-learned review

Key outcomes

Zero mailbox data loss across all workloads

Minimised user disruption during cutover

Clean target tenant with correct security posture
