SSKM reset, problems with new backups

Hi StefanS,

Thank you for reaching out to Sophos Community.

Is this about your case ID 06389319? And community post  RE: Firmware Upgrade from 17.5.12 to 18.5.2 not possible -> urgend 

Upon checking your case, I.T Support is inquiring if you have upgraded the firmware to 18.5-MR-5 and reach out if you still have any further issues.

Hi Erick Jan 
this is a new case, Case ID: 06394726
It is a different Sophos XG 230, with this FW a SSKM reset was performed and a new backup was generated.
The problem is that on the replacement firewall, on which this backup is to be restored,
the error message is displayed that the SSKM key is incorrect.

Hi StefanS,

Thank you for the correction.

• Do the two FW have the same Firmware version?
• Have you tried to Reset the SSKM again and then re-do another backup and try to upload on the replacement FW

I think i have found the bug.
On the appliance where this SSKM reset was performed, the backup mode was set to "Email".
After i switched to "Local" and saved the change, the newly created backup was encrypted with the new SSKM key.
Either there is a problem with the backup mode "Email" or it was enough to simply save the backup again.

Hi StefanS,

That is great to hear. To verify, you didn’t encounter any more errors once the local backup was restored to the replacement Firewall.

Also, I've seen that you have also updated your case with your findings.Kindly update us if you still encounter any more errors.
