Upgrading LTM HA Pair - disable network failover?

Hi All -   having successfully upgraded our standalone LTM unit from 9.3.1->9.4.8->10.2.1, I'm trying to find the recommended practice for upgrading our production HA pair - does this make sense: ...
config
design

9.4.8 is the support recommended path to 10.x:

 

"The upgrade path for LTM, in order to correctly roll forward your config, is ; go to version 9.4.8, confirm config is good, then do a v10 upgrade."

 

 

thanks for the link - I can't believe the "search F5" field does not seem to access those knowledgebase articles!

 

 

http://support.f5.com/kb/en-us/solutions/public/11000/200/sol11215.html?sr=15041414network_failover_mgmt says:

 

Temporarily set the Redundancy State Preference setting of both units to None. This action ensures that the BIG-IP systems will not swap roles unnecessarily during the procedure.

 

 

The doc goes on to say disconnect the unit you are upgrading from the networks except for mgmt (for heartbeats)

 

If the new & old High availability protocols are compatible then you are in luck otherwise you need downtime to complete the upgrade of the pair.

 

 

So is there non-disruptive path from my current 9.3.1 to latest 10.2.1 without downtime? (are the High availability protocols compatible?)

 

 

thanks
