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.](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.

Hi [@rc](https://community.neo4j.com/t5/user/viewprofilepage/user-id/14484) 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 ![γ‚Ήγ‚―γƒͺγƒΌγƒ³γ‚·γƒ§γƒƒγƒˆ 2022-07-28 22.13.24.png](https://us1.discourse-cdn.com/flex021/uploads/neo4jcommunity/original/3X/e/a/ea55b97db5a77f40bb5945a6099ee437a179c08c.png "γ‚Ήγ‚―γƒͺγƒΌγƒ³γ‚·γƒ§γƒƒγƒˆ 2022-07-28 22.13.24.png") ---

Hi [@rc](https://community.neo4j.com/t5/user/viewprofilepage/user-id/14484) 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.
