For initial data import (step 1) into Neo4j database I'm using the neo4j-admin import tool. There you can specify the internal id of a node by :ID in the header.
I would also like to use
LOAD CSV command for creating more nodes (step 2) into an already existing database (with data from previous step). I can't find the answer on how to specify internal id of a node by using this command.
Why it is not possible, while at initial import it is? In second step I'm having a similar csv files as in the first step, which means I have a csv file of nodes with first column being an id of a node AND I have a csv file of relationships between them with columns be like start_id,end_id,relationshipType.
