    You suggest you do it in a test environment before production deployment. It is good to seperate DC and ADFS for production deployment.

    In test environment, it really doesn’t matter and you can note down config settings, uninstall ADFS from DCs and re-install on other R2 servers.

    If this is your production environment, you have to communicate downtime to users first, then follow steps you did in test. Keep Microsoft PSS support number handy and good luck!
