Provide an example of how the cloud flow could be disabled and a PowerShell script using Get-AdminPowerAppConnection to get all the connections in an environment

Extend the example to use PowerShell with Dataverse API Use PowerShell and Visual Studio Code with the Dataverse Web API or Use bulk operation messages from a simple C# command line application to upload the results from PowerShell to the Connection Reference Identities

@Grant-Archibald-MS Suggested approach: - Validate PowerShell returns information similar to the connector - Create example of how to upload those results in batches to the Dataverse Table - Replicate the issue by creating large number of connections in an environment - Verify that the PowerShell command continues to work with large sizes above the 21MB issue above @Grant-Archibald-MS Also linking to #8031 [[CoE Starter Kit - Feature]: One off solution for too-many-connections](https://github.com//issues/8031) @Grant-Archibald-MS @DaveTheTeamsGuy @TomekPi it would be good to geed feedback on #8031 and the importance for you to help build on the PowerShell approach that @Jenefer-Monroe discusses above @mohamrizwa This issue is being closed as its scope is now included in a newly created consolidated enhancement request for centralized management of orphaned components (Apps, Flows, Connection References) in the CoE Starter Kit.
