SharePoint Architecture: 2026 Considerations for SharePoint Consulting

SharePoint Online tenant-to-tenant migration in 2026 is dominated by three approaches: native Microsoft 365 migration tools (free but limited to in-place tenant scenarios), ShareGate (best-in-class for permission preservation across hub-spoke architectures), and AvePoint Migrator (enterprise scale with regulated-industry compliance reporting). EPC Group selection criteria depend on user count, permission complexity, and audit-reporting requirements; typical enterprise migration runs 8-16 weeks at $150K-$450K all-in.

Microsoft Purview information protection on SharePoint Online has matured significantly through 2026: sensitivity labels can now auto-classify based on Microsoft 365 Copilot grounding hints, container labels enforce sharing controls at the site level, and Purview content explorer surfaces unauthorized PHI/PII exposure in real time. For HIPAA-regulated tenants, the combination of auto-labeling plus sensitivity-aware DLP plus Audit (Premium) 6-year retention is the audit-defensible posture.

Decision factors EPC Group evaluates

  • Microsoft Purview content explorer for unauthorized PHI/PII discovery
  • Hub-spoke information architecture redesign vs legacy flat-IA
  • Migration tool selection (Microsoft native vs ShareGate vs AvePoint) by complexity tier
  • Audit (Premium) configuration for 6-year retention
  • Sensitivity label rollout with auto-classification rules
