Configuration migration from virtual F5 to phisycal F5

I have a virtual F5 in QA environment. Due to the load and need, I want to upgrade it to big-ip LTM 2000. What is the easy way for me to migrate the configuration? We also change the external IP for the new F5. However, pool members are the same IP range. Except external IP for the VS, others are the same including pool member, pool member IP, monitor pool member settings, SSL certificate, cookies, http profiles, irules, and etc.(but no iAPP) I know that I need to config the basic network and HA. I was told that I can easy to just modify configuration file such as /config/bigip_base.conf and change virtual IP and then restore it back to the physical F5. Is this correct? Please advise.

  • By thew way...my version is 11.5.3 for the new physical F5 but the virtual F5 is 11.5.1.HF8
  • I would just load the UCS and ensure the new physical F5 is disconnected from the network before you press enter. Note that you'll need to load it with the 'no-license' option so as not to overwrite the physical F5's license file.

    tmsh load sys ucs xxxx no-license
    

    If it fails to load, it will have at least installed the config files, so you can carefully edit bigip_base.conf or bigip.conf as appropriate, and fix any errors until it does load (tmsh load sys config)

    Once loaded, use 'config' to set a new management IP address, then plug in the management interface, and use that to make any changes that are needed, using tmsh or the GUI.
