Merge 2 different nodes and associate all the realtions to the single merged node

[Awi]

In neo4j 2.0.3, can we merge 2 different nodes say node1 and node2, and all the relations associated with node1 and node2 will be then associate to the single merged node.

Thank-you

Unfortunately, you have to do it manually. Which API do you use?

Ok ... Thank-you Michael ... We are using Java API.

It is some manual work,

find the two nodes

for the node with the fewer rels (b) to the node with more rels (a)

copy all properties from a to b

iterate over b's relationships and recreate them with a and the end node, copy each relationship's properties

Done.

Yes Michael... we are taking the same approach... also we are taking care of duplicate relationships... Thank-you for your time

Check this post for merger of nodes with relationships.

This post has a nice explanation on how to merge nodes with its associated relationship.

Thanks
