Hi everyone, I need to upgrade an existing Aerospike 3.10.0.3 Cluster (mesh) to the latest version (4.5.0.4) without downtime. I tried to just add a new node with the acual version to the existing cluster, but in asadm, I cannot see the new node. On the new node, I also do not see the existing cluster, but only the new node. What is the way to perform the upgrade? Do I need to setup a complete new cluster? \_ Thomas ---
