Upgrade from 10.2.3 to 12.0.0

Hello,   I'm upgrading a pair of BIG-IP LTM VE 10.2.3(112) to the latest 12.0.0(606) in the lab. They're in active/standby mode with only one module provisioned: LTM. Network failover is enabled. ...

Thanks! The first outage is clear to me, I was wondering about the outage when both boxes run 12.0.

 

You see, when you start the upgrade Device A is in active mode and Device B is in standby. When you finish with the upgrade, Device B is active and Device A is in standby. When you initially force Device A to become active, this is where the outage happens. Once it's done, things get back to normal and both units keep connections table.
