• Upgrading from 4.50 thru 4.56 -----> 4.57, need to use the 4.57 GUI.
  • I tried to use v5.22 GUI to upgrade from 4.52 to 4.57 but it fails due to missing yocto_signature file.
  • Apparently 4.57 doesn't look for the yocto_signature file where as v5.22 does.
  • Note that if the steps in this article was ignored, and upgrade jump was to large from an older version, a reimage to the new version may still have an issue.
    • reimage may need to be at the original version first, then do the upgrade steps in this article.
    • symptoms recently found:
      • chassis original had older version 4.42 but upgraded to 5.30 causing no access to chassis
      • reimage to 5.30 allowed ssh access but not GUI access
      • reimage back to 4.42 allowed GUI access and able to upgrade following this article 
      • Note that in above symptoms that was found we also stopped at v5.04 due to Customer having older (obsoleted) modules
        • Some details:
          • reimage to 4.42

Downgrade

• The listed versions indicate the necessary intermediate steps:
  • 5.24 (or higher) -> 5.18-> 5.11 -> 4.95 -> 4.71 -> 4.57 -> lower than 4.57
• Note: Always use the higher level GUI version in each step.
• For example, say you are downgrading from 5.24 to 4.53
  • using the 5.24 GUI, downgrade to 5.18
  • using the 5.18 GUI, downgrade to 5.11
  • using the 5.11 GUI, downgrade to 4.95
  • using the 4.95 GUI, downgrade to 4.71 (could not downgrade directly from v4.95 to v4.57 because it looks for a yocto signature file which is not included with v4.57)
  • using the 4.71 GUI, downgrade to 4.57 (v4.71 doesn't look for the yocto signature file)
  • using the 4.57 GUI, downgrade to 4.53
