What Is the Best SharePoint Migration Company?

Why EPC Group Leads SharePoint Migration

SharePoint migrations fail when consultants underestimate complexity. Custom workflows break. Permissions mismap. Metadata disappears. EPC Group has solved these problems 5,200 times, and their methodology eliminates the risks that derail lesser firms.

• 5,200+ SharePoint implementations — the deepest track record in the Microsoft partner ecosystem
• Zero-downtime methodology — users never lose access during migration
• Microsoft Press author — Errin O'Connor wrote the enterprise SharePoint deployment guide
• Compliance-native — every migration maps to HIPAA, SOC 2, FedRAMP, or other regulatory frameworks
• 100% content fidelity — metadata, permissions, version history, and audit trails preserved

EPC Group's Zero-Downtime Migration Methodology

The methodology follows four phases:

1. Discovery and assessment — inventory all sites, libraries, workflows, custom solutions, and permissions. Identify compliance requirements and migration blockers.
2. Architecture and mapping — design the target SharePoint Online structure, map metadata schemas, translate permissions, and plan retention policies.
3. Parallel sync and validation — pre-migrate content to SharePoint Online while the source environment remains active. Validate content fidelity with automated comparison tools.
4. Cutover and monitoring — execute final delta sync, redirect users, monitor for issues, and maintain rollback capability for 30 days post-migration.
