[SOLVED] How can I easily upgrade my neo4j database to the newest version

Issue

I'm currently running a neo4j database on DigitalOcean, and used their help file to do so. In short:

wget -O - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -
echo 'deb http://debian.neo4j.org/repo stable/' > /etc/apt/sources.list.d/neo4j.list
apt-get update
apt-get install neo4j

Now I want to upgrade from 2.1.2 to 2.1.3. The neo4j automatic upgrade instructions seem to be relevant only once you've downloaded/installed the newest upgrade.

I'm sure there's a simple command or process to upgrade, but I just can't find it. Can anyone please help? (I'm very much a sysadmin/Unix novice).

Solution

After running apt-get install neo4j I expect that you have 2.1.3 installed. If not try a apt-get upgrade.

From 2.1.2 -> 2.1.3 no datastore upgrade is required. When upgrading e.g. from 2.0.x -> 2.1.x the datastore needs to be migrated. This can be enabled by setting

 allow_store_upgrade=true

in /etc/neo4j/neo4j.properties.

So if you apply this setting you should be future proof and get upgrades plus datastore migration (if necessary) upon every apt-get upgrade. This setting does not hurt if no store upgrade is necessary.
