In 2026, enterprises are rapidly shifting their collaboration ecosystems to modern cloud platforms—and SharePoint Online remains at the center of this transformation. Whether you’re planning to migrate to SharePoint, move from legacy versions like SharePoint 2010/2013/2016, or modernize a hybrid environment, having a clear and actionable roadmap is critical for success.
Why Enterprises Are Prioritizing SharePoint Migration in 2026
Organizations across industries are moving to SharePoint Online due to:
- Need for cloud scalability & lower operational costs
- Microsoft’s AI-powered capabilities through Copilot
- Modern site architecture & improved UX
- Integrated security & compliance
- End of support for legacy SharePoint versions
- Demand for hybrid and remote-friendly collaboration tools
Enterprises that migrate from SharePoint on-premises to SharePoint Online gain faster performance, simplified management, and improved governance through the SharePoint Administration Center.
