Upgrade from Neo4J 3.3.3 Community to Neo4J 3.5 Enterprise

I currently have Neo4J 3.3.3 community installed on the server and I want to upgrade to Neo4J 3.5. I have a few questions to clarify before I do that:

  1. Will it be sufficient to simply install the new database and to point it to the existing community datastore as well as uncommenting the dbms.allow_upgrade=true? Or should there be any additional measures taken?

  2. Does it make sense to upgrade directly to Neo4J 4 or better to upgrade to 3.5 first?

  3. Do I need to reinstall the APOC tools for the new version?

  4. How does the admin in the enterprise version work? I recall that the enterprise version comes with some kind of extra interface. Is it available via Linux? Do I access it via the browser :7474 (or whatever my Neo4J port is)?

Thank you!

To answer the questions:

First, you need to upgrade to the latest 3.3.latest and only then to 3.5.latest.

  1. You need to copy the database (in /database/ folder) either manually or using the neo4j-admin dump command as well as the dbms folder with user management. Leave a backup somewhere else. Then uncomment the dbms.allow_upgrade=true and launch the DB

  2. First to the latest version of 3.5, then to Neo4j 4?

  3. Yes. The appropriate APOC for 4.0

  4. The admin is accessible at :7474 (or the port you choose for insecure bolt). Desktop version can be downloaded separately.
