neography / neo4j change relationship end point to

问题:

i am using neography as wrapper of the REST api for Neo4j graph database. I often need to change the end node of a relationship, but i am not able to do this using neography.

Of course, i can delete the relation then recreate it with the new end point node, but it's not optimized.

Does anyone had this problem?

Thanks.

Neo4j does not allow replacing the nodes of a relationship (see javadoc). So you only can create a new relationship to the new end node and delete the other relationship.
