How to replace two 3600 in Sync-failover mode by two 4000 devices

Hi there, asking for good practice to substitute our 3600 devices by the 4000 series. Can or should this be done like this: 1. Backup 3600 config ie tmsh save /sys ucs 2. Restore this config on both 4000 device ie tmsh load /sys ucs 3. Establish network connections between the 4000 devices 4. Renew license

 

Many thanks for any hint! Rainer

    Hi,

     

    Depending on which version you're running on, you have two options :

     

    • 11.4.0 minimum : You can make heterogeneous cluster

       

    • Others : Your idea is the one I usually use.

    be careful with your licenses - each device has its own license, so check out the "load sys ucs" no-license flag when you are loading the UCS onto the new BIGIPs. it also never hurts to create archives of the new 4000s after you've activated their own licenses in the event something goes awry during the 3600-ucs load.
