The upgrade procedure replaces the software catalog. Changes that you made to
the software catalog will be lost. If you have added new SRL images in the
software catalog, you need to modify the software catalog and then upload the
SRL images.
For instructions, see Updating software catalog to include new versions in the Fabric Services System User Guide. You need to complete this step before you access the Fabric Services System for any changes.
