Before Upgrade – Important!

2. To ensure a successful upgrade, run the Upgrade Advisor Tool with your current configuration and the target version. Then, perform the required actions as instructed in the report output. The Upgrade Advisory Tool includes all the limitation and upgrade considerations specifically relevant to the source configuration, version, device details and target version. Make sure to update the Upgrade Advisory Tool DB before performing the analysis. The Upgrade Advisor Tool is available on the Customer Portal.

Additional Considerations

Important!
*For Alteon 5208, 5424, 5820, 6024, 7612, 7220, and 9800, vADCs running this version require ADC-VX running at a minimum version 33.0.0.0.
*For Alteon 8420, vADCs running this version require ADC-VX running at a minimum version 33.0.1.0.
*For Alteon 6420, vADCs running this version require ADC-VX running at a minimum version 33.0.4.50.
Downgrade
Configuration rollback (downgrade) is not supported. The configuration should be saved before upgrading to a newer version. If you perform version rollback, Radware recommends the following procedure:
1. Set the configuration block for the next boot to factory (the management port setting can be kept).
2. Change the image for the next boot to the image to which you want to roll back.
3. Perform reboot.
4. After reboot, Alteon will run with the previous version with the factory default configuration.
5. Upload the configuration that was saved before the version upgrade
