Context Graph in Spectrum Technology Platform 2023.1 stores models on an instance of Neo4j Graph Database Server that is separate from the Spectrum server. For an upgrade to Spectrum Technology Platform 2023.1, you must install Neo4j Graph Database Server in either a stand-alone or cluster server configuration. As a best practice, you should always back up models and property files on the currently installed version of Context Graph before you upgrade Spectrum Technology Platform. After you perform the upgrade, you will export the models and then import them into the Neo4j Graph Database Server database. Context Graph Repository Configuration settings in the Management Console specify the IP address or host name and port to connect to a Neo4j Graph Database Server instance (or to nodes for a clustered server configuration).
