v11 upgrade without downtime for active/standby pair?
Were running active/standby pairs of v10.2.3 that are connected with the fail-over serial cable.
I've upgraded a couple BIGIP's to v11 using the guide F5 provides:
The guide describes a procedure which involves shutting down interfaces on the BIGIP devices, and at one point both the active and passive unit have all their interfaces shut down, which of course means that there is an interruption to the service.
The problem is that I need to upgrade environments where downtime is hard to schedule.
Does anyone know of a way to avoid downtime for the pair?
Thanks in advance,
