10.2.0 to 10.2.4 upgrade

Hi,

I am looking at upgrading an active/standby high availability pair of BigIP's from 10.2.0 to 10.2.4. I have read SOL9057 that states that version 10.x runs the same protocol and ports for network failover, but it doesn't state if they use the same payload.

So can anybody please confirm if version 10.2.0 and 10.2.4 run the same network failover payload and hence I can then upgrade one unit in the pair to 10.2.4 whilst still running its peer on 10.2.0 (the older version), then failover to the unit running 10.2.4 before upgrading the other unit?

Thanks,

Doug
