For a new Exchange DAG, I would first compare the current Client Access configuration before applying the same namespace to both servers.

I recently published ExchangeURLManager.ps1 for this type of work.

It can review one or multiple Exchange servers, configure Internal/External URLs and the Autodiscover SCP, compare source and target servers, and clone supported settings when required.

Clone is comparison-only by default. If changes are applied, the script shows a Preview, asks for confirmation, creates a fresh JSON backup, applies the required changes, and verifies the result afterward.

Supported authentication settings can also be included explicitly during Clone.

You can find the script here:

I documented the usage examples and screenshots here:
