Need help with migration WDM 5.5.1 from one server to another

Hello, I need to migrate WDM 5.5.1 between servers without loosing connectivity for Wyse Thin OS Clients. I would like to move repository, rapport db and certs. I don't know if there can be two WDM Servers on a network at the same time to migrate the data. Maybe someone have done something similar and could help with steps to take to migrate it succesfully. I'm not sure if I can just backup sql database Rapport from SQL Server Management Studio and import it to the second server. And after succesfull is there anything to change on Wyse devices to connect to the new server.
