I need to upgrade an existing Aerospike 184.108.40.206 Cluster (mesh) to the latest version (220.127.116.11) 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
