Existing Customers
If you are a MoveData customer prior to September 2025, then there is nothing you explicitly need to do.
If you do choose to install MoveData via Setup → Apps → Connected Apps → Manage Connected Apps then you must re-authenticate MoveData after completing this action. To do so, go to MoveData → Settings → General → Authorise MoveData and click "Authorise". More information about the authorised user is available here.
New Customers
MoveData will automatically install as an authorised connected app.
