My graph has approximately 27 million relations and 15 million nodes. When I try to start neo4j instance with the graph.db database that was created using neo4j import tool, I get the following error:

sudo service neo4j status
● neo4j.service - Neo4j Graph Database
 Loaded: loaded (/lib/systemd/system/neo4j.service; disabled; vendor preset: enabled)

Try uncommenting this line in neo4j.conf, as I think neo4j-import-tool was not yet upgraded to support 3.2.x version.

# Enable this to be able to upgrade a store from an older version.
#dbms.allow_format_migration=true
