Switch instances - HA No Downtime Possibility
In an HA environment where a Load Balancer is properly
distributing traffic between the nodes - There is a possibility of avoiding downtime by migrating only one node at any
given time. While having a Load Balancer forwarding requests to other working nodes.
Note
Within the same Artifactory cluster, you can run multiple nodes with different Operating System versions. For example, one node may run RHEL 7 while another runs RHEL 8. However, you cannot run a cluster with nodes using different Artifactory versions. All nodes in the cluster must use the same Artifactory version.
