Hi, . Not sure what exactly I should check in this article. I found statement about same hardware as well as some email confirmation I received from F5 support that this statement is valid for session data.

Sure it was some time ago, as well as doc I am referencing is for 11.5.3 so maybe this limitation is no more there.

Here is link Managing Connection Mirroring and statement is:

Important: Connection mirroring only functions between devices that reside on identical hardware platforms.

    The link I've posted just states that mixed cluster environments are available by using v11.4+ "Starting in 11.4.0, the BIG-IP system supports high availability (HA) features, such as ConfigSync and failover between different hardware platforms. By allowing HA functionality between different hardware platforms, newer hardware platforms only need to join the current device group to receive the older hardware platform's configuration." You may want to open a new question on the LTM board or may ask F5 directly to get sure? Cheers, Kai
