On-premises versions of SharePoint have an audit feature that ShareGate Migrate can access to generate an audit report. This report gives you a breakdown of various user actions on your sites.

You see this error message when you try to see the results of a scheduled Audit report for your Microsoft 365 environment:

ShareGate Migrate's Audit report does not support Microsoft 365 environments

Microsoft phased out the classic auditing feature in SharePoint online in favor of a unified audit Log. The unified log can encompass other Microsoft 365 elements, such as Teams and Exchange.

The unified audit log is not currently supported in ShareGate Migrate.

You can run audits directly in the Microsoft 365 Security & Compliance Center.
