M365 Migration SME - Senior Associate

Experience: 4+ years

Location: Hyderabad, Kolkata, Bangalore

Type: Hybrid

Employment Type: Full-time

Role Summary:

We are seeking a Senior Associate specializing in Microsoft 365 migrations to plan and execute complex tenant-to-tenant and on-premises-to-tenant transitions. This role focuses on end-to-end migration delivery across Exchange Online, SharePoint Online, OneDrive, Teams, and Intune-managed devices, with strong identity, mail flow, and security/compliance awareness. The ideal candidate is hands-on, detail-oriented, fluent in migration tooling and automation, and comfortable communicating status, risks, and technical details to stakeholders.

Key Responsibilities:

- Discovery and assessment:

 - Inventory users/mailboxes (including archives, shared/resource mailboxes, public folders), distribution lists, transport rules, SharePoint sites, OneDrive content, Teams (channels, posts, apps, tabs, Planner), line-of-business integrations, and Intune-managed device fleets.

 - Assess identity, domain, and mail flow dependencies, throttling constraints, compliance holds/retention, and application interdependencies.

- Migration design and readiness:

 - Define migration strategies (coexistence vs. cutover, staged waves, pilot/early adopters, back-out plans) for Exchange, SharePoint/OneDrive, Teams, and devices.

 - Plan hybrid Exchange prerequisites, MRS endpoints, domain and DNS changes, accepted domains/connectors, and network throughput windows.

 - Establish user mapping, permission/ACL translation, and content scope with validation criteria.

- Execution and validation:

 - Perform tenant-to-tenant and on-premises-to-tenant migrations using native capabilities (e.g., Exchange Online MRS, Migration Manager, SharePoint Migration Tool) and third-party tools as needed.

 - Execute mailbox, site, and Teams content migrations; reconcile permissions, versions, metadata, shares/links, and channel messages where supported.

 - Migrate or re-establish policies/rules (transport rules, DLP, retention) and validate post-migration functionality (mail flow, sharing, search, apps).

 - Deliver Intune/device migration plans: Autopilot hardware IDs export/import, device re-enrolment, compliance/configuration policy re-targeting, and application redeployment.

- Troubleshooting and cutover leadership:

 - Resolve common issues (large/corrupt items, throttling, failed batches, EWS/Graph/API limits, blocked file types/customizations).

 - Lead wave cutovers, coordinate communications, execute runbooks, and provide hypercare; manage defect triage and remediation.

- Identity and mail flow:

 - Normalize UPNs/SMTP addresses, design Entra ID Connect/hybrid identity, cross-tenant sync/B2B strategies, GAL/free-busy, and calendar/resource migrations.

 - Configure connectors, journaling, DKIM/DMARC/SPF, safe sender lists, and integrate third-party gateways if applicable.

- Security and compliance considerations:

 - Account for Purview retention/holds, label behavior, eDiscovery, audit implications, and reapplication of labels/policies post-migration.

 - Align Conditional Access, MFA, and device compliance baselines with the target tenant’s security posture.

- M365 Government migrations:

 - Plan and execute migrations to/from GCC, GCC High, or DoD tenants, factoring licensing, connectivity constraints, data residency, feature parity, and tooling limitations.

- Tooling and automation:

 - Use and optimize migration tools (e.g., Sharegate, BitTitan MigrationWiz, Quest On Demand, AvePoint, Cloudiway, SkyKick) and Microsoft native features.

 - Develop scripts for automation and reporting (PowerShell, Graph API), build dashboards, and produce validation reports.

- Documentation and communication:

 - Produce migration runbooks, mapping matrices, testing plans, cutover/hypercare guides, and operational handover documents.

 - Provide clear status, risk/issue tracking, and stakeholder updates; support end-user communications and training materials.

Required Qualifications and Experience:

- 8+ years of enterprise IT experience with 5+ years hands-on delivering Microsoft 365 migrations across Exchange Online, SharePoint Online, OneDrive, Teams, and Intune devices.

- Proven delivery of tenant-to-tenant and on-premises-to-tenant migrations at scale (thousands of users), with wave planning, coexistence, and minimal downtime.

- Strong technical expertise in:

 - Exchange Online and hybrid (MRS, connectors, mail flow, transport rules, public folders, shared/resource mailboxes).

 - SharePoint/OneDrive content migration, permissions/metadata, and link remediation.

 - Teams migrations and limitations; experience with third-party tooling for Teams content and app/tab migration.

 - Intune device migration and re-enrolment, Autopilot, compliance/configuration policies, app distribution, and Windows Update for Business.

 - Entra ID (identity, Conditional Access, MFA, PIM, cross-tenant sync/B2B).

- Working knowledge of Microsoft 365 Government (GCC/GCC High/DoD) migration constraints and compliance frameworks (e.g., FedRAMP, CJIS, ITAR).

- Proficiency with PowerShell and Microsoft Graph for automation, reporting, and API-based migrations.

- Familiarity with throttling, service limits, error handling, and performance optimization during migrations.
