deployments
The following table lists the supported upgrade paths for SmartFabric OS10 in Full Switch mode deployments.
NOTE:
Follow the validated upgrade paths listed in this table before you upgrade to the latest release. Ensure that you back
up the configuration data and license files in an external storage. The notation A » B indicates that OS10 supports direct
upgrade from Release A to Release B.
NOTE: For instructions about upgrading OS10 on a pair of VLT nodes, see Upgrade OS10 on VLT nodes with minimal traffic
loss.
NOTE: If you are deploying an OS10 switch that has a factory-loaded older version of the OS10 software, Dell Technologies
recommends that you download the latest version of the software and perform a fresh installation. See Installing
SmartFabric OS10 section for details.
