Downgrading firmware may cause auto-restores to fail


Applies To:

GRV-EPIC-PR1

Versions Affected:

1.1.0 to 1.3.2

Resolved In Version:

1.4.0


Symptoms:

With the following combination of circumstances, an auto-restore will fail:

  • You are downgrading from any of the following versions to any firmware version lower than the one you are starting with:
    • 1.2.x
    • 1.3.x
    • 1.4.0
  • Before you start the firmware update, you select the auto-restore feature available for that version of firmware.
  • Any of the components that are part of the auto-restore have settings that are incompatible with an earlier version. (An example of an incompatibility is described in KB88014.)

Workaround:

Before you start the firmware update, make a backup of your settings. After the upgrade finishes, check the settings. If any returned to factory defaults and you expected them to be restored, do a partial restore of those settings from the manual backup that you created.

Resolution:

Opto 22 has resolved this issue.
