Syntax for neo4j v5 (deprecation)

[nrouyer]

In Neo4j 5.9, creating a node or relationship entity, and then referencing that entity in a property definition in the same CREATE clause is deprecated. Split the CREATE clause into two separate clauses instead.

As a consequence, in the racks section, instead of:

// Racks
WITH 10 as racks
MATCH (dc:DataCenter {name:"DC1"})
MATCH (nr:Network:Zone) // one per zone
WITH * UNWIND range(1,racks) AS rackid
CREATE (dc)-[:CONTAINS]->(rack:Rack {name:"DC1-RCK-"+nr.zone+"-"+rackid, rack:rackid, zone:nr.zone})-[:HOLDS]->(s:Switch {ip:nr.ip+"."+rackid, rack:rackid})-[:ROUTES]->(si:Interface {ip:s.ip+".254"})<-[:ROUTES]-(nr);

We should now have:

// Racks
WITH 10 as racks
MATCH (dc:DataCenter {name:"DC1"})
MATCH (nr:Network:Zone) // one per zone
WITH * UNWIND range(1,racks) AS rackid
CREATE (rack:Rack {name:"DC1-RCK-"+nr.zone+"-"+rackid, rack:rackid, zone:nr.zone})
CREATE (s:Switch {ip:nr.ip+"."+rackid, rack:rackid})
CREATE (si:Interface {ip:s.ip+".254"})
CREATE (dc)-[:CONTAINS]->(rack)-[:HOLDS]->(s)-[:ROUTES]->(si)<-[:ROUTES]-(nr);

As well the index creation should be updated for neo4j 5.

Instead of:

create index on :Software(name);

We should now have:

CREATE INDEX IF NOT EXISTS FOR (s:Software) ON (s.name);
