SharePoint has an audit feature that the ShareGate migration tool can access to generate the audit report. This report gives you a breakdown of various actions your users performed in your sites.
Symptoms
You see this error message when you are trying to see the results of a scheduled audit report for Microsoft 365:
Microsoft 365 no longer supports auditing.
Error Code
- CR-426-055
Details
Microsoft phased out the classic auditing feature in SharePoint online in favor of a unified audit Log. The unified log has the advantage of encompassing other Microsoft 365 elements such as Teams and Exchange.
The unified audit log is not currently supported in the ShareGate migration tool.
Solution
You can only run audits directly in the Microsoft 365 Security & Compliance Center.
