If the requirement is to have only one working Artifactory node in standalone mode, the below steps can be followed:

A. Please stop both the Artifactory nodes in the HA cluster.

B. Then in the system.yaml file located in the $JFROG_HOME/artifactory/var/etc directory of the First node, comment out the below-highlighted options under the shared.node
## Node Settings
  node:
    id: "art1"
    ip: xx.xx.xx.xx
    #haEnabled: true
    #taskAffinity: any
    #primary: true

C. It is also required to change the binarystore.xml template in the First node from the 'cluster' configuration binary provider, such as cluster-s3-storage-v3,cluster-file-system, etc, which is required for HA setup to the respective non cluster binary provider config which is required for standalone setup as in this link.

D. We would also need to change the cluster license file by renaming the ‘artifactory.cluster.licenses’ file (located in the $JFROG_HOME/artifactory/var/etc/artifactory) to ‘artifactory.lic’ which is required for a standalone Artifactory instance.
After following the above steps, please start the above Artifactory node in order to use it as a single standalone node.
