Legacy SharePoint Modernization: Challenges, Benefits, and Best Practices

Many organizations have relied on SharePoint for years to manage documents, collaboration, intranets, workflows, and business information. Over time, however, older SharePoint environments can become difficult to manage.

Legacy sites may contain outdated content, classic pages, custom code, complex permissions, older workflows, and business processes that no longer reflect how teams work today.

This is where Legacy SharePoint Modernization becomes important.

Modernization is not simply about moving existing SharePoint content to a newer environment. It is about assessing what an organization has today, deciding what should be retained, redesigning what needs improvement, and creating a more manageable Microsoft 365 environment.

Microsoft's modernization guidance recommends approaching the process through assessment, strategy, execution, and ongoing support.

What Is Legacy SharePoint Modernization?

Legacy SharePoint Modernization is the process of transforming older SharePoint environments into modern, easier-to-manage platforms that better support current business requirements.

Depending on the environment, modernization may involve:

• Moving SharePoint Server content to SharePoint in Microsoft 365
• Converting classic SharePoint experiences to modern experiences
• Replacing outdated workflows and custom applications
• Restructuring sites, libraries, and navigation
• Reviewing and simplifying permissions
• Removing obsolete or duplicate content
• Improving search and content discoverability
• Integrating SharePoint with Microsoft 365 services
• Establishing stronger governance and lifecycle management

The goal is not to modernize everything automatically. Instead, organizations should determine which sites, applications, workflows, and content still provide business value.

Why Are Organizations Modernizing Legacy SharePoint?

Older SharePoint environments can continue to support business operations, but maintaining them indefinitely can create technical and operational challenges.
