Upgrade considerations
The following considerations help you determine whether to follow a standard or non-standard upgrade procedure:
• Downgrades—Special guidelines apply when you downgrade firmware to an earlier version. See
“Downgrading firmware”. In some cases, the downgrade path requires reimaging. Take care to study the release notes for each version in your downgrade path.
• Re-imaging—If you are installing a firmware version that requires a different size of system partition, you might be required to re-image the boot device.
Important: Read the release notes for release-specific upgrade considerations.
