Upgrade guide for our team to upgrade our 2.3.5 database to latest 3.0.x

Upgrade_Neo4j_DB_to_3_0.md

Taking clues from 2.3.9 release notes and 2.3.8 deployment upgrade

following 3.0 docs

Run these commands from the '/usr/local/share' directory

To 2.3.9

1. shut down the database sudo /usr/local/share/neo4j/bin/neo4j stop or neop
2. wget dist.neo4j.org/neo4j-community-2.3.9-unix.tar.gz
3. tar -xzf neo4j-community-2.3.9-unix.tar.gz
4. mv neo4j-community-2.3.9 neo4j
5. copy the data folder in /usr/local/share/neo4j

• cp -r /usr/local/share/neo4j/data/* /usr/local/share/neo4j-community-2.3.9/data/

sed -i.bak s/#org.neo4j.server.webserver.address=0.0.0.0/org.neo4j.server.webserver.address=0.0.0.0/g neo4j-community-2.3.9/conf/neo4j-server.properties
sed -i.bak s/dbms.security.auth_enabled=true/dbms.security.auth_enabled=false/g neo4j-community-2.3.9/conf/neo4j-server.properties
sed -i.bak s/org.neo4j.server.webserver.https.enabled=true/org.neo4j.server.webserver.https.enabled=false/g neo4j-community-2.3.9/conf/neo4j-server.properties

7. Recommended to turn on automatic upgrade, even though it doesn't seem to do anything.

"Set the Neo4j configuration parameter allow_store_upgrade=true in the conf/neo4j.properties file of the 2.3.8 installation. Neo4j will fail to start without this configuration."

8. check everything ran right. sudo /usr/local/share/neo4j/bin/neo4j start

To 3.0.x

Make sure you have openjdk8.0 installed
