    kgaigl , 
    it is highly recommended to do that in a maintenance Window , specially if you have " voice " services or FTP applications on you Big-ip device. 
    if your services are web application only , you will not feel by impact during your action. 
    > I have do this before with 2 devices in HA , on of them was faulty and when getting the RMA new device , I installed it with the other node without any impact. 
    - I Broke the HA and device Trust and Configure the HA and build the trust from Scratch again , and it worked fine.
