Replacing faulty SG210 in HA setup

PatrickLaw

Hi,

I have a set of SG210 running UTM 9.510-5 firmware with active subscription.

Recently 1 of the SG210 had problem and we RMA the unit, a replacement unit was sent to us, but with a higher firmware version (9.705). I checked the Sophos UTM download page and seems UTM 9.510-5 is no longer available for download any more.

May I know what is the correct procedure to join the replacement unit back to the HA cluster?

1. Backup config file from existing working SG210
2. Go to MyUTM, license for the old faulty unit and change the serial number to the new unit
3. Go to High Availability setting in the existing working SG210 and change the operation mode to Off
4. Upgrade existing SG210 to same firmware as the replacement unit (downtime expected)
5. Connect the HA ports for both units
6. Configure HA setting at existing unit
7. Connect the WAN and LAN port of replacement unit

Is the above steps correct?

Thanks.

Patrick.

    Hi guys,

    Was thinking of doing the following steps:

    1. Load UTM 9.510-5 to replacement unit (sent email to Sophos support to request for ISO)
    2. Backup config from working unit and load to replacement unit
    3. Connect replacement unit and sync for HA

    However there is no response from Sophos for days, so I used the following steps:

    1. Update replacement unit to 9.705-7
    2. Backup config from existing unit and load into replacement unit
    3. Update existing unit (with some downtime)
    4. Connect replacement unit and sync for HA

    So far ok.

    Thanks guys.
