Project Overview

The Oregon Department of Justice (DOJ) is executing an enterprise content management (ECM) modernization initiative to migrate approximately 45+ TB and 19M+ files from legacy repositories into a modern Microsoft SharePoint Online architecture hosted within Microsoft 365 Government Community Cloud (GCC).

The source environment includes Alfresco (27 TB across 135 sites / ~13M items), Windows network file shares (18 TB across the Child Advocacy & Protection Division and Medicaid Fraud Unit), and selected legacy SharePoint Online sites.

This project directly aligns with DOJ’s Cloud First strategy and the Legal Tools Program (LTP). The SharePoint architecture will integrate with JusticeNexus, a Dynamics 365 / Power Platform application serving as the authoritative system for legal case and matter management.

Scope of Work & Responsibilities

1. Target Operating Model (TOM) & Architecture Validation

• Review and validate DOJ's finalized ECM Target Operating Model (TOM), taxonomy schemas, metadata fields, naming conventions, and Entra ID group-based RBAC permissions structures.

• Validate legal/case-related content mapping rules to ensure strict alignment with JusticeNexus folder structures, metadata indicators, and security boundaries.

2. Repository Assessment & Pre-Migration Readiness

• Perform technical scans across Alfresco, SMB file shares, and existing SharePoint sites.

• Identify and resolve unsupported file formats, path length violations (>400 characters), illegal characters, large objects, and migration throughput constraints.

3. Tooling & In-Boundary Staging Configuration

• Deploy, configure, and manage enterprise migration tools strictly within DOJ’s GCC authorization boundary (Azure Government storage/compute or DOJ-managed on-premises infrastructure). External vendor-hosted SaaS platforms are prohibited.

• Design and orchestrate job batching, concurrency, and automated backoff/retry logic against Microsoft 365 GCC API limits to mitigate HTTP 429 throttling during full wave and delta synchronization runs.

4. Pilot & Wave Execution

• Execute pilot migrations using DOJ-managed, isolated service accounts.

• Plan and execute production waves, division freeze windows, and delta synchronization passes, preserving version history, file integrity, and metadata.

5. Validation, Auditing & Acceptance

• Deliver end-of-wave reconciliation reports validating item counts, checksum/hash integrity, permissions accuracy, and audit trails/chain of custody.

• Remediate migration exceptions, permissions discrepancies, and broken embedded Office document links.

6. Training, OCM & Hypercare

• Provide role-based technical instruction for Information Services staff and Site Owners covering metadata taxonomy, retention administration, and Entra ID permissions operations.

• Deliver administrator and end-user runbooks, and provide post-cutover hypercare support integrated directly with DOJ helpdesk workflows.

Required Qualifications

• 7+ years of hands-on experience in Enterprise Content Management (ECM) and large-scale data migrations to Microsoft SharePoint Online.

• Proven track record migrating multi-terabyte repositories from Alfresco Content Services and Windows SMB file shares into SharePoint Online.

• Deep, hands-on experience operating inside Microsoft 365 Government Community Cloud (GCC) environments and adhering to government boundary constraints.

• Proven experience deploying enterprise migration tools (AvePoint Fly, ShareGate, Quest Migration Manager, or native MS Migration API) in sovereign/private-boundary deployments (no external SaaS data processing).

• Advanced scripting skills in PowerShell (PnP.PowerShell, SharePoint Online Management Shell) and familiarity with Microsoft Graph API.

• Comprehensive knowledge of Microsoft Entra ID (Azure AD), Role-Based Access Control (RBAC), Privileged Identity Management (PIM), and Conditional Access.

• Must be a U.S. citizen or permanent resident located in the Continental United States and able to pass a background check prior to equipment issuance.

Preferred Qualifications

• Familiarity with Microsoft Dynamics 365 or Power Platform document management integrations.

• Experience with Microsoft Purview (retention schedules, sensitivity labels) and Microsoft Syntex.

• Relevant Microsoft certifications (e.g., Microsoft 365 Certified: Enterprise Administrator Expert).

• Prior experience working with state, federal, or justice/law enforcement entities (e.g., CJIS standards).
