Firmware Upgrade - Grandstream Networks UCM6300 Series High Availability User Manual

FIRMWARE UPGRADE

To ensure that there is no service interruption in HA setup, upgrading UCM requires user to follow below
steps strictly:
Step 1: Log in the web UI of the standby UCM (A), upload firmware via web UI and the standby UCM will
reboot. Wait for it to boot up.
Step 2: After the standby UCM (A) boots up, log in the web UI of the active UCM (B) and check the HA web
page. "Force Switch" button on the UCM B's HA web page will be available. Press it to manually trigger
switchover. After switchover, UCM A will become active and UCM B becomes standby.
Step 3: After switchover, log in UCM B and upload firmware to its web UI. UCM B will reboot and request
data from UCM A for full backup.
In short, when upgrading UCM in HA setup, the standby UCM needs to be upgraded first and becomes
active UCM. Then we can upgrade the standby UCM. This will ensure the active UCM is always working
and providing PBX functions, so there is no service interruption during upgrading or switchover.
