Technical Business Analyst - Microsoft 365 Migration

Technical Business Analyst - Microsoft 365 Migration

Remote - must be UK based. Salary £50,000 - £60,000, depending on experience.

Have you led application discovery and dependency mapping during a complex IT migration. Can you investigate technical evidence in Entra ID and Microsoft 365, then explain your findings clearly to clients. Would you enjoy taking ownership from initial discovery through to application testing and cut-over.

We are working with a growing Microsoft technology consultancy looking for an experienced Technical Business Analyst to support a global Microsoft 365 tenant consolidation programme.

We are particularly interested in people from a technology consultancy or MSP background who combine hands-on technical analysis with confident client communication, curiosity and enthusiasm. Your experience should include investigating how applications connect, identifying migration dependencies and turning those findings into test plans and practical recommendations.

The Role

The programme will consolidate European and Asia Pacific Microsoft 365 tenants into an existing North American tenant. Your work will run in two connected stages: establishing how the application estate works today, then planning and carrying out testing with the client to support a successful migration.

During discovery, you will:

• Lead the analysis of SaaS and on-premises applications, mapping authentication, integrations, data flows and dependencies.
• Investigate Entra ID enterprise applications, app registrations, sign-in and audit logs, alongside evidence from other Microsoft 365 services.
• Use PowerShell and Microsoft Graph to extract and validate information.
• Review documentation and run focused sessions with regional IT specialists and third-party suppliers.
• Identify configuration conflicts, risks and gaps that could affect migration.
• Direct the work of a Data Analyst and maintain clear application inventories, dependency maps and impact assessments.

You will then own the application and dependency test plan, including:

• Creating test scenarios, test cases and acceptance criteria.
• Coordinating system integration testing and UAT with client teams.
• Carrying out testing during build, pilot and dress rehearsal.
• Tracking defects through to resolution and checking application access after cut-over.
• Reporting readiness and providing evidence for test sign-off and Go/No-Go decisions.

What We Are Looking For

You will need at least five years' experience as a Technical Business Analyst, Systems Analyst or in a comparable role, including analysis on software development or business system implementations.

Your experience will need to include:

• Leading application discovery and dependency mapping during a merger, separation, data centre move or tenant migration.
• Writing test plans and test cases, and running UAT with business users.
• Working with SaaS and on-premises applications.
• Knowledge of Entra ID enterprise applications, app registrations, service principals, SSO and Conditional Access.
• Understanding networking dependencies and Exchange Online mail flow.
• Using PowerShell and Microsoft Graph for data extraction.
• Strong Excel skills and clear technical documentation, including process flows and dependency diagrams.
• Working with global teams and third-party suppliers.

Microsoft 365 or Entra ID tenant-to-tenant migration experience would be an advantage.

Your Approach Matters

You will be working closely with clients, technical specialists and delivery colleagues, so how you communicate is just as important as the quality of your analysis. We are looking for someone who builds rapport, asks focused questions, listens carefully and explains technical findings in a way others can act on.

You will also need to be comfortable working with incomplete information. Access to business stakeholders is limited, so you will use technical evidence and targeted conversations to establish the facts, making any remaining gaps clear.

Previous consultancy or MSP experience would be particularly valuable. Above all, you will bring a personable, professional approach, enthusiasm for the work and the initiative to keep things moving.
