I tried enabling this property, but the server still fails to start.
Here's what I've tried:
===
# Stopping the server
$ ./bin/neo4j stop
# Removing existing 'graph.db'
$ rm -rf ./data/graph.db
# Copying the sample db from 'bacth-import'
$ cp -r /data/gordon/sources/batch-import/target/graph.db ./data/
# Verify the upgrade propery
$ grep "upgrade" conf/*
conf/neo4j.properties:# Enable this to be able to upgrade a store from an
older version
conf/neo4j.properties:allow_store_upgrade=true
# Start the server
$ ./bin/neo4j start

The 'console.log' still says:
Detected incorrectly shut down database, performing recovery..
But 'data./graph.db/message.log' has this to say:
===
$ tail ./data/graph.db/messages.log
Caused by:

Any ideas how to fix it ?
Thanks!
