Just not quite sure what I've been doing wrong here.
I had the neo4j database 2.1.5 working fine under linux(except being slow). so I tried to upgrade to 2.2 version.
These are the step I took:
1. stop 2.1.5
2. copy from 2.1.5/data/graph.db to 2.2/data/graph.db
3. allow-store-upgrade=true
4. start 2.2 by using command ./bin/neo4j start
However, I keep getting this error:
Failed to start within 120 seconds.Neo4j Server may have failed to start, please check the logs.
I've been on it for a while now. any suggestion what am I doing wrong here?
EDIT:
This is the end of my messages.log file :
Caused by: org.neo4j.kernel.impl.storemigration.StoreUpgrader$UpgradingStoreVersionNotFoundException: 'neostore.nodestore.db' does not contain a store version, please ensure that the original database was shut down in a clean state.
