SharePoint Online Overview
SharePoint Online is the hosted version of SharePoint — part of the Microsoft 365 subscription. Microsoft manages the infrastructure, updates, and security.
- No servers to buy, maintain, or patch.
- New features delivered continuously — sometimes weekly.
- Microsoft 365 integration: Teams, OneDrive, Exchange, Power Platform, Copilot.
- Compliance: FedRAMP High (GCC High), HIPAA, SOC 2, GDPR — managed by Microsoft.
- AI features: Microsoft Copilot, SharePoint Premium, Viva Connections, and Microsoft Search Copilot integration.
SharePoint Server Overview
SharePoint Server is the on-premises version — installed and managed by your IT team. Microsoft provides software and patches; you manage everything else.
- You control the update schedule — no forced feature changes.
- Requires Windows Server, SQL Server, and SharePoint Server licenses plus hardware.
- Farm solutions and classic add-ins are supported (though retiring in Online).
- SharePoint Server Subscription Edition is the current version — older releases (2019, 2016, 2013) are in extended support or end of life.
- No AI features — Copilot, SharePoint Premium, and Viva Connections are Online-only.
Which Should You Choose?
For almost all organizations in 2026, SharePoint Online is the right choice.
Choose SharePoint Online if:
- You want AI features: Copilot, SharePoint Premium, or Viva Connections.
- You need regulated-industry compliance: HIPAA, FedRAMP, SOC 2, GDPR.
- You want to eliminate server infrastructure and patching overhead.
- You have remote workers who need reliable access from any device or location.
- You want continuous feature delivery rather than a scheduled update model.
Consider SharePoint Server only if:
- You have regulatory mandates that explicitly require on-premises data custody — read the regulation; most do not.
- You operate a classified government environment where GCC High certification does not yet meet your requirements.
- You have legacy custom code dependencies that would cost more to remediate than a 5-year cloud migration saves.
Migration: On-Premises to SharePoint Online
Most organizations migrate from SharePoint Server to SharePoint Online in six phases.
- Assessment — inventory sites, customizations, workflows, and compliance requirements.
- Content cleanup — remove ROT content (typically 30–40% of total volume) before migration.
- Architecture design — map on-premises site collections to SharePoint Online hub-spoke structure.
- Pilot migration — validate tools on 2–3 representative sites before full execution.
- Wave-based migration — 5–10 TB per wave with user acceptance testing between waves.
- Cutover and decommission — final sync, URL redirects, 30-day parallel run before retiring the on-premises farm.
Frequently Asked Questions
Should I choose SharePoint Online or SharePoint Server?
For almost all organizations in 2026, choose SharePoint Online. Microsoft invests exclusively in SharePoint Online — AI features, Purview governance, and Viva Connections are all Online-only.
SharePoint Server receives security patches only. The only exceptions are organizations with genuine on-premises data custody mandates or highly classified government environments.
What is the main difference between SharePoint Online and SharePoint Server?
SharePoint Online is hosted by Microsoft in the cloud and receives continuous feature updates. SharePoint Server is installed on your own servers and updated on your schedule.
Microsoft Copilot, SharePoint Premium, and Viva Connections are Online-only. SharePoint Server supports farm solutions and classic customizations that are retiring in the Online environment.
Can I migrate from SharePoint Server to SharePoint Online?
Yes, EPC Group has completed over 6,500 SharePoint migrations. The duration of each migration ranges from 4 to 16 weeks, depending on the amount of data.
For permission preservation, we recommend using:
- ShareGate
- AvePoint Migrator
Additionally, please note that workflows from SharePoint 2010 and 2013 must be rebuilt in Power Automate, as they cannot be migrated directly.
Is SharePoint Online HIPAA compliant?
Yes, Microsoft 365 is HIPAA-eligible under a Business Associate Agreement (BAA). It includes features that help meet HIPAA requirements:
- SharePoint Online with Microsoft Purview
- Sensitivity labels
- DLP policies
- Retention labels
- Audit logging
Configuration by an experienced consultant is required — the platform provides the tools but compliance requires proper design.

Frequently Asked Questions
Should I choose SharePoint Online or SharePoint Server for my organization?
SharePoint Online is recommended for most organizations due to automatic updates, zero infrastructure maintenance, built-in disaster recovery, and included compliance features. SharePoint Server is best for organizations with strict data sovereignty requirements, air-gapped networks, or heavy customizations incompatible with the cloud.
How much does SharePoint Online cost compared to SharePoint Server?
SharePoint Online Plan 1 starts at $5/user/month, and it is included in Microsoft 365 Business and Enterprise plans. SharePoint Server requires server licenses ($7,500+), SQL Server licenses, CALs ($100+ per user), hardware, and IT staff for maintenance. TCO for SharePoint Server is typically 3 to 5 times higher over a 5-year period.
Can I migrate from SharePoint Server to SharePoint Online?
Yes, Microsoft provides the SharePoint Migration Tool (SPMT) for free, and third-party tools like ShareGate and AvePoint offer advanced migration capabilities. Key considerations include custom solutions, InfoPath forms, legacy workflows, and large file libraries. EPC Group typically recommends a phased migration approach.
Does SharePoint Online support custom code and solutions?
SharePoint Online supports the SharePoint Framework (SPFx) for custom web parts and extensions, Power Automate for workflows, and Power Apps for custom forms. However, full-trust solutions and farm solutions from SharePoint Server are not supported and must be redesigned using modern development patterns.
Is SharePoint Server still being updated by Microsoft?
SharePoint Server Subscription Edition (SE) is the latest on-premises version with continuous feature updates. However, Microsoft is investing primarily in SharePoint Online with AI-powered features like Copilot, SharePoint Premium, and Syntex. On-premises editions receive security updates but fewer new features.

SharePoint Architecture: 2026 Considerations for SharePoint Online Vs SharePoint Server
In 2026, modern SharePoint information architecture uses the hub-spoke pattern. This includes:
- 1 root hub for each business unit
- 5-15 spoke sites for every hub
- Mega-menu navigation linked to Viva Connections
- Sensitivity-label-driven sharing controls
Legacy SharePoint farms that migrate to this structure often experience significant benefits. They typically see:
- 60% faster content discovery
- 40% fewer 'where do I save this?' helpdesk tickets
- 100% sensitivity-label coverage within 90 days
In 2026, SharePoint Online tenant-to-tenant migration mainly uses three methods:
- Native Microsoft 365 migration tools: These are free but limited to in-place tenant scenarios.
- ShareGate: This tool is best-in-class for preserving permissions across hub-spoke architectures.
- AvePoint Migrator: This option is designed for enterprise scale and includes regulated-industry compliance reporting.
EPC Group evaluates several factors when selecting a migration strategy. These include user count, permission complexity, and audit-reporting needs.
A typical enterprise migration lasts between 8 and 16 weeks. The total cost ranges from $150K to $450K.
Decision factors EPC Group evaluates
- Sensitivity label rollout with auto-classification rules
- 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
