Neo4j Community Edition 3.0.1 failed to start

I populated Neo4j database using Gremlin console 3.1.2. Checked that data is persistent by exiting the above console and then go back to it pointing to my local database location:

>graph=Neo4jGraph.open('/MyNeo4jDB/graphdb')
>g = graph.traversal()
>g.V()
==>v[0]
==>v[1]
==>v[2]
==>v[3]

Working on Windows 7 Professional. I also checked that directory C:\MyNeo4jDB\graph.db has been created and populated with files. I would like to see visual representation of my data by using "Neo4j Community Edition 3.0.1" but got the error "Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@3c5e750c was successfully initialized, but failed to start". I know that Neo4j Community Edition 3.0.1" is working fine to display another database. What is the reason that Neo4j Community Edition failed to open my database? Any help will be appreciated.

You have to upgrade your database.

Set in neo4j.conf (you can reach it via the "Options" pane in the starter)

dbms.allow_format_migration=true
