Hi Balazs,
you have to manually copy all nodes and relationships from one to the
other database. I have written a tool for that and posted some code here
[1].
But take care, in the posted version in [1], relationship properties
were not copied. To fix that, you have to replace
s.createRelationshipTo(e, r.getType());
by
Relationship newRelationship =
s.createRelationshipTo(e, r.getType());
for (String key : r.getPropertyKeys()) {
newRelationship.setProperty(key, r.getProperty(key));
}
I hope this is useful for you.
Greetings
Axel
