Dear Everyone, I am attempting to upgrade from version 3.5.13 to 4.0. I keep getting the error: Could not find a compatible version of graph algorithm. I have read the log file, but most of it is outside of my knowledge base at the moment. I hav pasted the log below. Could someone assist me with this? 2020-02-04 16:43:22.091+0000 ERROR Failed to start Neo4j: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabaseService@558b4942' was successfully initialized, but failed to start.

Looks like you have some plugins installed. The logs only mention [APOC](https://github.com/neo4j-contrib/neo4j-apoc-procedures), but you also mentioned [graph-algorithms](https://github.com/neo4j-contrib/neo4j-graph-algorithms). - Graph Alogrithms latest [3.5.4.0](https://github.com/neo4j-contrib/neo4j-graph-algorithms/blob/3.5.4.0) is built for Neo4j 3.5.3. - Check [APOC 4.0 release notes](https://github.com/neo4j-contrib/neo4j-apoc-procedures/releases/tag/4.0.0.0) for Neo4j 4.0 compatabilities. The short answer is, remove all your plugins first, and find supported versions. I believe APOC is the only plugin that has been updated for Neo4j 4.0 as of yet. The longer answer is to carefully read the [4.0 migration guide](https://neo4j.com/docs/migration-guide/4.0/), and the [Neo4j 4.0 release announcement](https://community.neo4j.com/t/latest-neo4j-major-release-4-0-available/13747). ---

Hello Tony, Thank you for that explanation. I look forward to the day that I can make sense of the logs. I'm just getting into Neo4J, and it is quite something. Kind regards, Tideon ---

Hello Tony, New issue after the install. It asked me to enter the password. Which seems odd. But it isn't accepting the password I am giving it. So I attempted to reset the password I get the error: Set password failed: Error: Failed to change the password What do I do now?

Hello Tony, Also when I go over to the browser to do a query, I get the following error. #### Neo.TransientError.Database.DatabaseUnavailable Database 'graph.db' is unavailable. Kind regards, Tideon ---
