    Sure, But its a 2 step process. Restore configuration to one new device, get it working, retire old device. Upgrade new device to a cluster.

     

    On the old (current) device, start bash. Run this command f5mku -K record the string printed. It is the masterkey. On the new device BEFORE YOU RESTORE THE UCS set the masterkey with

     

    f5mku -r

     

    Your ucs will then restore and the configuration will load if it has passwords. otherwise it might restore but not load that configuration!!!!

     

    Restore the ucs from the cli so you can use the no-licence no-platform options. (Platform-migrate is useless IMHO)

     

    The configuration will quite likely not load because the naming of interfaces has changed slightly on some platforms. Fix by editing /config/bigip_base.conf and load the config with

     

    tmsh load sys config

     

    repeat until its right and you are done!

     

    When thats working, save your configuration and start on on HA.

     

    (When you are in a HA group, the masterkey will be a property of the group.)

     

    PS: Version 14.1 is now out. Use that!
