Hi, Noticing that the latest Neo4j Enterprise release was available today, I downloaded it and gave it a try.
On trying to start the DB I noticed that there was a message saying that I need to set dbms.allow_format_migration=true Following setting this parameter, the DB started with no apparent errors: 2017-05-12 08:27:01.207+0000 INFO ======== Neo4j 3.2.0 ======== 2017-05-12 08:27:01.605+0000 INFO No SSL certificate found, generating a self-signed certificate.. 2017-05-12 08:27:06.233+0000 INFO Starting... 2017-05-12 08:27:14.724+0000 INFO Bolt enabled on 127.0.0.1:7687. 2017-05-12 08:27:14.942+0000 INFO Initiating metrics... 2017-05-12 08:27:17.608+0000 ERROR Neo4j cannot be started, because the database files require upgrading and upgrades are disabled in configuration.
