Frequently Asked Questions
How long does an enterprise cloud migration take?
Enterprise cloud migration timelines vary: small organizations (under 100 users) take 2-4 weeks, mid-sized (100-500 users) take 4-8 weeks, and large enterprises (500+ users) typically take 3-6 months. EPC Group uses phased migration approaches with zero-downtime cutover to minimize business disruption.
What cloud platforms does EPC Group migrate to?
EPC Group specializes in Microsoft Azure, Microsoft 365 (Exchange Online, SharePoint Online, OneDrive, Teams), and hybrid cloud environments. We also handle migrations from AWS and Google Cloud Platform to Azure, tenant-to-tenant consolidations, and on-premises to cloud transitions.
How do you ensure zero data loss during migration?
We use a multi-phase approach: pre-migration assessment and inventory, parallel sync during migration (delta sync), validation checksums on every migrated item, and post-migration auditing. Our 6,500+ migration track record maintains a 99.99% data integrity rate with zero data loss across all enterprise engagements.
Can you migrate while maintaining compliance (HIPAA, SOC 2, FedRAMP)?
Yes. EPC Group has deep expertise in compliance-regulated migrations. We maintain chain-of-custody documentation, encrypted data transfers, audit trails, and compliance validation at every phase. We have completed migrations for healthcare (HIPAA), financial services (SOC 2), and government (FedRAMP) organizations.
What is the cost of enterprise cloud migration?
Cloud migration costs depend on scope: small business migrations start at $15K, mid-sized organizations range from $50K-$150K, and large enterprises with complex hybrid environments cost $200K-$500K+. EPC Group provides fixed-price quotes after a discovery assessment. Our pricing includes project management, migration execution, testing, and post-migration support.

Migration Strategy: 2026 Considerations for Services Cloud Migration
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.
Azure Confidential Computing (DCadsv5/ECasv5 series) is the privileged-data play for 2026: AMD SEV-SNP and Intel TDX enclaves protect data IN USE (in addition to at-rest and in-transit encryption), enabling regulated workloads (clinical analytics with PHI, financial services M&A modeling, federal IL5) to run on shared Azure infrastructure with cryptographic attestation that the host operator cannot inspect the data.
Decision factors EPC Group evaluates
- Microsoft platform capability assessment
- Vendor consolidation analysis
- Compliance and governance posture review
