In this post, we'll discuss how to migrate data from other databases like MySQL, PostgreSQL, Oracle, and Cassandra to Neo4j using Scala. We've covered the basics of getting started with Neo4j in Scala and defining user-defined procedures and APOC library usage previously. To perform data migration, it's essential to keep the Neo4j APOC Kit in the `$Neo4j_Home/plugins` folder. The post aims to guide readers through connecting and transferring data from these databases to Neo4j, starting with PostgreSQL.
