Legacy SharePoint Modernization: Challenges, Benefits, and Best Practices

This is particularly important when legacy environments contain large numbers of unique permissions. Microsoft recommends paying close attention to permission scopes and simplifying complex permission structures where possible.

Better Microsoft 365 Integration

A modern SharePoint environment can become part of a broader Microsoft 365 ecosystem involving Teams, OneDrive, Power Automate, Power Platform, Microsoft Search, and other services.

Instead of SharePoint operating as an isolated repository, modernization can help position it as part of a connected digital workplace.

Common Challenges in Legacy SharePoint Modernization

Modernization projects often involve more than technical migration.

1. Complex Customizations

Custom web parts, master pages, workflows, scripts, third-party solutions, and integrations can make modernization more complicated.

Not every customization has a direct modern equivalent. Some may need to be redesigned, rebuilt, or retired.

Organizations should create an inventory of custom components before deciding on a migration approach.

2. Outdated and Redundant Content

Years of content accumulation can make it difficult to determine what should actually move.
