apoc.refactor.rename.type
Procedure
apoc.refactor.rename.type(oldType String, newType String, rels [Rel], config Map<String, Any>) - renames all relationships with type 'oldType' to 'newType'.
If a list of relationships is provided, the renaming is applied to the relationships within this list only.
== Signature
apoc.refactor.rename.type(oldType :: STRING?, newType :: STRING?, rels = [] :: LIST? OF RELATIONSHIP?, config = {} :: MAP?) :: (batches :: INTEGER?, total :: INTEGER?, timeTaken :: INTEGER?, committedOperations :: INTEGER?, failedOperations :: INTEGER?, failedBatches :: INTEGER?, retries :: INTEGER?, errorMessages :: MAP?, batch :: MAP?, operations :: MAP?, constraints :: LIST? OF STRING?, indexes :: LIST? OF STRING?)Input parameters

Usage Examples
The examples in this section are based on the following sample graph:
CREATE (mark:Engineer {name: "Mark", city: "London"})
CREATE (jennifer:Engineer {name: "Jennifer", city: "St Louis"})
CREATE (michael:Engineer {name: "Michael", city: "Dresden"})
CREATE (jim:Engineer {name: "Jim", city: "London"})
CREATE (alistair:Engineer {name: "Alistair", city: "London"})
MERGE (jim)-[:COLLEAGUES {since: date("2006-05-01")}]->(alistair)
MERGE (mark)-[:COLLEAGUES {since: date("2018-02-01")}]->(jennifer)
MERGE (mark)-[:COLLEAGUES {since: date("2013-05-01")}]->(michael);The following changes the relationship type between Jim and Alistair from COLLEAGUES to FROLLEAGUES:
MATCH (:Engineer {name: "Jim"})-[rel]->(:Engineer {name: "Alistair"})
WITH collect(rel) AS rels
CALL apoc.refactor.rename.type("COLLEAGUES", "FROLLEAGUES", rels)
YIELD batches, total, timeTaken, committedOperations
RETURN batches, total, timeTaken, committedOperations;| batches | total | timeTaken | committedOperations |
