The following points are taken from the [Up gradation Link](http://neo4j.com/docs/stable/deployment-upgrading.html#explicit-upgrade)
`1. Cleanly shut down the older version of Neo4j, if it is running.
2. Install Neo4j 2.1.5, and set it up to use the same database store directory (typically data/graph.db).
3. Set the Neo4j configuration parameter allow_store_upgrade=true in your conf/neo4j.properties file. Neo4j will fail to start without this configuration set.
4. Start up Neo4j.
5. The database store upgrade will occur during startup.
6. The allow_store_upgrade configuration parameter should be removed, set to false or commented out.
7. Information about the upgrade and a progress indicator are logged into the messages.log file, inside the database store directory.`

The sixth point, After starting the higher version of neo4j, should we again set `allow_store_upgrade=false`. 
 I have followed the same steps, but the older database which was 10gb after upgrading to new version, database size is only 1.7gb. 
I am worried, all my relations that are imported in older version can be seen in newer version?
Any suggestions.
