    vrrp should interop between vendors. 


    • So you should be able to add one of the Juniper switches to the existing vrrp group. 
    • Once a member you can configure the backup ports and cut them over to the Juniper switch.
    • Retire one of the two existing devices as it migrates off.
    • add in the second new Juniper switch.
    • Change mastership over to one of the Juniper
    • Continue to swing the remaining ports until complete
