Reporting To: The IT Director
Role Overview
This role provides the technical leadership and hands‑on delivery required to continue a multi‑phase collaboration platform consolidation programme across the group. The programme is migrating several business units onto a single Microsoft 365 tenant, retiring legacy Google Workspace and standalone Microsoft 365 environments along the way. You will be responsible for overseeing in‑flight migrations, planning and executing future migrations, and decommissioning environments that have already been transitioned. The work spans Microsoft 365 tenant‑to‑tenant migrations, Google Workspace to Microsoft 365 migrations, and the coexistence, cutover and stabilisation activities that surround them.
Migration Delivery
- Take ownership of in‑flight and upcoming platform migrations, including both Microsoft 365 to Microsoft 365 (tenant consolidation) and Google Workspace Enterprise to Microsoft 365 transitions.
- Design and execute migration approaches for mail, calendars, contacts, files, chat and identity, using the Microsoft Migration Toolset (Exchange Online migration, SharePoint and OneDrive migration tooling) and complementary third‑party tooling where appropriate.
- Manage coexistence periods where dual systems operate in parallel, including mail flow configuration, calendar interop, free/busy visibility, and delta synchronisation.
- Plan and execute cutover activities including domain MX changes, primary SMTP swaps, UPN transitions, and the controlled retirement of source environments.
- Write and maintain PowerShell scripts that interact with Exchange Online, Microsoft Graph, Entra ID and SharePoint for bulk operations, validation, reporting and automation.
Discovery and Analysis
- Develop a thorough understanding of source environments before migration, including users, groups, mail, files, shared drives, calendar resources, chat, third‑party integrations and operational workflows.
- Use Google Admin tools, GAM, Microsoft Graph, PowerShell, Microsoft Migration Manager and other appropriate tooling to query, analyse and report on source data.
- Identify migration risks, edge cases and dependencies, including shared mailboxes, delegations, calendar resource booking, SaaS authentication dependencies, and cross‑document references such as Google Sheets IMPORTRANGE.
- Document findings and recommend approaches to address them.
Identity, Licensing and Coexistence
- Plan and implement identity strategies that accommodate Entra ID, Google federation and the broader SaaS application landscape during transitions.
- Manage licensing transitions across Microsoft 365 and Google Workspace, including Cloud Identity downgrades for retained identity‑only accounts.
- Maintain mail flow integrity across domains during coexistence, including accepted domain types, forwarding configurations, primary SMTP and alias management.
Tenant Decommissioning
- Oversee the controlled decommissioning of source environments after successful migration, covering data retention, identity downgrade, licence release and tenant retirement.
- Coordinate retention of legacy native content as a safety net where required.
- Manage SaaS application transitions from legacy identity providers to Entra ID single sign‑on.
Stakeholder Engagement and Proposal Support
- Provide the technical analysis and detailed planning required by the IT Director and CTO to build migration proposals for leadership approval.
- Communicate progress, risks and decisions through Steering Committee forums.
- Translate technical detail for non‑technical audiences in user communications, change management materials and service desk guidance.
Post‑Migration Support
- Provide hyper‑care support during and after migration cutovers.
- Engage directly with senior stakeholders and VIP users to triage and resolve complex issues.
- Iterate on the support model based on real‑world feedback and post‑migration metrics.
Qualifications
Essential:
- Strong administrative expertise in Microsoft Entra ID, Microsoft 365 (Exchange Online, SharePoint Online, OneDrive, Teams) and Google Workspace Enterprise.
- Proven experience delivering tenant‑to‑tenant Microsoft 365 migrations and Google Workspace to Microsoft 365 migrations.
- Strong PowerShell skills, including writing scripts that interact with Microsoft Graph, Exchange Online and Entra ID for import, export, validation and automation tasks.
- Hands‑on experience with the Microsoft Migration Toolset (Exchange Online migration, SharePoint Migration Manager, OneDrive migration) and Google Workspace administration tools including GAM.
- Practical understanding of mail flow during migration: accepted domain types, MX cutover, forwarding, primary SMTP and alias strategies, and calendar interop configuration.
- Experience decommissioning Google Workspace and Microsoft 365 tenants in a controlled way, including identity‑only downgrades to preserve SaaS authentication where needed.
- Ability to communicate complex technical concepts to both technical and non‑technical stakeholders.
- Strong analytical and problem‑solving skills, with the patience to work through edge cases methodically.
- A proactive, solution‑oriented mindset and the ability to manage multiple migration workstreams simultaneously.
Desirable:
- Familiarity with third‑party cloud migration tooling such as Movebot, CloudM or BitTitan.
- Experience administering Atlassian (Confluence, Jira) and Slack, including merging or consolidating instances.
- Experience with Intune and Kandji device management during platform transitions.
- Awareness of Microsoft Purview sensitivity labelling and DLP, and the impact these have on migration tooling and post‑migration document workflows.
- Power Platform familiarity for rebuilding migrated automations.
