Not out of the box. What you can do is to export the smaller databases, e.g. to Cypher script with the APOC procedure library, <https://github.com/neo4j-contrib/neo4j-apoc-procedures> using CALL apoc.export.cypher.all("/tmp/export.cypher",{});
Then run the resulting file with neo4j-shell bin/neo4j-shell -file /tmp/export.cypher The only requirement to actually MERGE your graphs is that each of your entities has a unique constraint set up for its "primary key" so that the export script uses those to get-or-create the nodes.
