then step is just
- no disconnect any cable
- upgrade standby box (unit 2) to 9.1.2 >> 9.3.1 >> 9.4.8 >> 10.2.4 (volume)
- reboot into 10.2.4
- failover from 9.1.2 (unit 1) >> 10.2.4 (unit 2)
- Test
- Do the same with unit 1
Is there no active-active problem with this step? correct me please Thank you
