BigIP 4200 Active/Standby <> Change Management IP/Hostname

I made the same changes on my devices using following steps:

• set standby device to force offline
• change IP/Hostname of standby device
• release offline standby device
• force standby active device (if needed make standby device to active manualy)
• set standby device to force offline
• change IP/Hostname of standby device
• set up Device trust (device 1 new IP, device 2 new IP)
• release offline standby device

In my network environment I didn't use maintenance window for this changes, there was no traffic failures. If you have complex network configuration it's better to use maintenance window.
