BIGIP LTM 3400 and 3900

I currently have 2 BIGIP LTM 3400's and want to purchase 2 3900's to replace them. I only have funding for one right now so I was wondering if the 3400 and 3900 will work together as an HA pair as long as they are running the same version of software?

    Hi Mike,

     

     

    As long as the units are on the same version it should work. But F5 won't support mixed platforms and/or versions in an HA pair. I'd definitely recommend you test the configuration before trying it in a production environment.

    During our rollout of new hardware we did do a mixed pairing. There are certain options that you need to make sure dont exist. for eg if a b db provision.extramb variable is changed based on the 3900 ( say you allocate 2 GB to host) and sync this config, you will end up choking the 3400. 3600 vs 3400 was a stretch, but we managed to make it work for the transition (couple of months). 3900 vs 3400 might be stretching that further.
