Neo4j showing error on switching versions

Question

I am having my java program for Neo4j with the Neo4j version as 2.3.0m1 .The jar files i was using for the connect was neo4j-desktop-2.3.0-M01.jar . Everything works fine. Now i want to load databases from 2.3.0-m3 version which is not opening in the current version. I am not able to find any jar files for this new version either .

This is my java code

import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.Node;
import org.neo4j.graphdb.Relationship;
import org.neo4j.graphdb.Transaction;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;


public class Testing {
public static void main(String args[])
{
    System.out.println("hai");

    GraphDatabaseFactory dbFactory = new GraphDatabaseFactory();
    GraphDatabaseService db= dbFactory.newEmbeddedDatabase("D:\\graph.db");

    try (Transaction tx = db.beginTx()) {
        System.out.println("began transaction");

        tx.success();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
       System.out.println("Done successfully");

}
} 

This is the error i am getting if i try to open a higher version db (from 2.3.0-M3)

Also i am trying to download the enterprise version zip(2.3.0-M1) for windows from neo4j web site because i have the import-graphml feature in 2.3.0-M3 for which i want to move up to 2.3.0-M3.But the link provided in neo4j site is not downloading it completly. http://neo4j.com/artifact.php?name=neo4j-enterprise-2.3.0-M01-windows.zip Is there somewhere else this can be downloaded from

Answer 1

If you are doing upgrade of Neo4j you also need to upgrade database version.

neo4j.properties

# Enable this to be able to upgrade a store from an older version.
allow_store_upgrade=true
