Following a Microsoft 365 update, the migration tool (version 17.0 and above) and cloud copy module work with a new version of the Azure ShareGate migration app. A Global admin must re-consent the Azure app to use the latest version.
The new Azure app adds a few permissions required to provide the best migration and management experience for Microsoft Teams and Microsoft 365 Groups.
If you do not consent to the new version of the Azure app, the permissions of the previous version will still be effective. However, you will experience some limitations from the limited set of delegated permissions.
For more information on the delegated permissions used by the Azure ShareGate migration tool app, see Which permissions does the Azure ShareGate migration tool application need?
The previous version of the Azure ShareGate migration tool app is not uninstalled when you consent to the new one.
It will not affect your experience to have both Azure apps. If you want to remove the old app, see How do I remove the Azure ShareGate migration tool app?
