Microsoft 365 Migration Consultant

JOB SUMMARY We are seeking an experienced Microsoft 365 implementation partner (vendor or contractor) to lead a multi-tenant consolidation project, unifying the organization's current fragmented environment, a 10-year-old UK (.co.uk) tenant, a sub-1-year-old US (.com) tenant, and Google Workspace environments in Australia and New Zealand (also less than a year old) — into a single .com tenant using Microsoft 365 Multi-Geo architecture. The successful partner will provide strategic guidance, hands-on technical delivery, and risk management throughout the consolidation, with particular focus on data residency compliance, identity management continuity (Entra ID), and minimal business disruption across all four regions (UK, US, Australia, New Zealand). JOB RESPONSIBILITIES Strategic Advisory — Provide guidance on the proposed single-tenant, multi-Geo consolidation approach, including identification of constraints, risks, dependencies, and recommended sequencing. Multi-Geo Architecture & Data Residency — Design and implement Microsoft 365 Multi-Geo configuration to ensure appropriate data residency for UK and ANZ users/workloads in compliance with regional requirements. Tenant Migration — UK — Plan and execute migration of the legacy (~10-year-old) UK .co.uk tenant into the unified .com tenant, with attention to the complexity and historical configuration accumulated over a decade. Tenant Migration — ANZ — Plan and execute migration of Australia/New Zealand workloads from Google Workspace into the unified Microsoft 365 .com tenant, including mail, identity, and collaboration tools. Identity & Access Management — Ensure Entra ID remains central to the consolidated environment, preserving and/or enhancing automated joiner/mover/leaver (JML) processes across all regions. Risk & Change Management — Identify migration risks (data loss, downtime, compliance gaps, user disruption) and develop mitigation and rollback strategies. Documentation & Knowledge Transfer — Provide implementation documentation, architecture diagrams, and runbooks to support internal IT teams' post-migration. Stakeholder Coordination — Work with Manuka Global's internal IT and regional business stakeholders across UK, US, Australia, and New Zealand to align timelines and minimize business impact. (Potential, longer-term) IT Operations Partnership — Subject to successful project delivery, scope for an ongoing IT Ops support relationship.
