SLX-OS Software Downgrade Considerations

• If a feature is new for the current version of your software, the feature will not function if you downgrade your version.
• Software downgrades to previous versions are prohibited when security parameters are configured for HTTPS support.
• CFM configurations are not compatible with versions earlier than SLX-OS 17r.2.01.
• To downgrade from a 64-bit to a 32-bit system or from 4.14x to 2.6x kernel versions, use the firmware download command with the fullinstall option.
• Before downgrading to a version that does not support RADIUS accounting, disable both login and command accounting.
• Before downgrading to a version that does not support RADIUS accounting, remove the source interface for the RADIUS configuration.
• After downgrading from an enhanced routing profile, perform an additional reload to ensure that the hardware profile is enabled.

Always refer to the release notes for compatibility information and for any restrictions about upgrades and downgrades under particular circumstances.
