When migrating Remote Desktop Services, which role should be migrated first?

Migrating the Remote Desktop Connection Broker first is crucial due to its role in managing user connections within Remote Desktop Services. The Connection Broker is responsible for directing user sessions to the appropriate Remote Desktop Session Host, which is essential for maintaining session continuity and load balancing across different session hosts.

If you migrate the Connection Broker first, it enables a smoother transition for the remaining components since it will continue to manage incoming session requests and direct them appropriately. This makes it easier to bring the other roles online one by one without interrupting service, as the Connection Broker will handle the connections to the existing Remote Desktop Session Hosts during the migration process.

While all roles are important in a Remote Desktop Services deployment, starting with the Connection Broker minimizes potential downtime and user disruption, ensuring that connections can be established and maintained throughout the migration process.
