Upgrading from simple node to cluster topologyhttps://community.appian.com/discussions/f/administration/9636/upgrading-from-simple-node-to-cluster-topologyDears, we have a very ok installation 7.6 that we need to upgrade and potentially go for a different topology, from single node installation to cluster installation. Does anyone knows if this is feasible, and the steps for doing this?

Please note that 7.6 is no longer supported and if you are planning on major architectural changes, then it is highly recommended for you to review possibility of upgrade to newer version of Appian prior to changing over to the new High Availability solution.<br /><div style="clear:both;"></div>
