Hello,
I am a neo4j newbie.
I am trying to upgrade my Neo4j desktop GDS library so that I can use the knn filtered algorithms. I am running Neo4j desktop version 1.4.15 (database version 4.4.5) which installs GDS version 2.0.3 by default. I need the GDS library version 2.1.0 and above.
I managed to download the libs from here: https://github.com/neo4j/graph-data-science/releases.
I copied the latest gds lib into my plugins folder and removed the old one. However I cannot start the database. This is the error in the logs:
ava.lang.RuntimeException: Error starting Neo4j database server at /Users/reenaclifton/Library/Application Support/Neo4j Desktop/Application/relate-data/dbmss/dbms-70518021-2834-47d5-8e35-645266dfc241/data/databases at org.neo4j.graphdb.facade.DatabaseManagementServiceFactory.startDatabaseServer(DatabaseManagementServiceFactory.java:228) ~[neo4j-4.4.5.jar:4.4.5] at org.neo4j.graphdb.facade.DatabaseManagementServiceFactory.build(DatabaseManagementServiceFactory.java:181) ~[neo4j-4.4.5.jar:4.4.5] at com.neo4j.server.enterprise.EnterpriseManagementServiceFactory.createManagementService(EnterpriseManagementServiceFactory.java:38) ~[neo4j-enterprise-4.4.5.jar:4.4.5] at com.neo4j.server.enterprise.EnterpriseBootstrapper.createNeo(EnterpriseBootstrapper.java:20) ~[neo4j-enterprise-4.4.5.jar:4.4.5] at org.neo4j.server.NeoBootstrapper.start(NeoBootstrapper.java:142) [neo4j-4.4.5.jar:4.4.5] at org.neo4j.server.NeoBootstrapper.start(NeoBootstrapper.java:95) [neo4j-4.4.5.jar:4.4.5] at com.neo4j.server.enterprise.EnterpriseEntryPoint.main(EnterpriseEntryPoint.java:24) [neo4j-enterprise-4.4.5.jar:4.4.5] Caused by: org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.procedure.impl.GlobalProceduresRegistry@5353dd09' was successfully initialized, but failed to start.

I would be grateful if anyone can assist with upgrading to the latest version of gds.
Many thanks,

Hi @rc
I have created two Neo4j databases.
The first is GDS 2.0.3 and Neo4j 4.4.5.
The second is GDS 2.1.6 and Neo4j 4.4.8.
These two databases work.
So I moved graph-data-science-2.1.6.jar to neo4j 4.4.5 /plugin and deleted graph-data-science-2.0.3.jar.
After restarting
Normal operation

Hi @rc
The downloadable version of the neo4j-graph-data-science-2.1.6.jar was also Good.
1. neo4j-graph-data-science-2.1.6.jar (Download version name)
2. graph-data-science-2.1.6.jar (Neo4j Desktop install version name)
Also, the db upgrade is available.
