It is suggested to perform the upgrade on a versioned Code System, for this reason, the Code System Version is always set to the latest extension Code System version. Although, if needed, the non-versioned Code System itself can be selected as well.
Start Snow Owl and select the Code System which has available upgrades from the Code System Selector.
Navigate to the Code Systems View and double click on the Code System which has an available upgrade to reveal its properties in an Editor.
Press the Upgrade Code System... button and chose the Code Systems that take part in the upgrade process. Then press Finish to start the upgrade process.
A dialog opens after the successful upgrade Code System creation. As it suggests to maintain the newly created Code System restart the Snow Owl client and select the Code System with the formerly defined Code System ID.
