Hi Graham,

 

 

Typically the HA communication (network failover, connection/persistence mirroring) doesn't change within minor releases (10.2.x for example). Here's a solution which describes the network failover over the versions:

 

 

sol9057: Service port and protocol used for BIG-IP network failover

And connection/persistence mirroring:

 

 

sol7225: Transport protocol used for BIG-IP connection and persistence mirroring

 

https://support.f5.com/kb/en-us/solutions/public/7000/200/sol7225.html

 

 

Also, if you're using hardwire failover, you don't need to worry about any potential changes to network failover across versions. The standby unit will stay standby.

 

 

If you want to be safe, you can always disable the switch ports on a standby device while you're upgrading it. If you're using VLAN or gateway failsafe, you can disable it temporarily while the switch ports are down to prevent the unit from restarting/rebooting.
