Hi Piyush, Thanks for your question. NiFI is a very powerful tool that can do a vast range of operations right out of the box. These are my personal opinions so feel free to accept or ignore them
NiFi is very flexible at transferring data between different database sources as you are trying to do. This is the main documentation for NiFi version 2.x. There is documentation for version 1.x separately on the same website. http://nifi.apache.org/documentation/https://nifi.apache.org/documentation/ This shows how to connect NiFi to Neo4j using the CData JDBC driver, but the steps are very similar for other JDBC drivers. https://www.cdata.com/kb/tech/neo4j-jdbc-apache-nifi.rst This page is a basic overview of setting up NiFi and running with Neo4j. There are much more detailed NiFi setup instructions you can find by googling but this one mentions Neo4j so I sent it. https://xclave.co.uk/2019/12/13/neo4j-nifi-getting-nifi-running/ Other Things to Consider Note that NiFi is in the process of a major functionality upgrading from version 1.x (1.27 is the latest GA of 1.x) to 2.0 which is not GA yet, but is getting close. I recommend you work with the the version 2.x (2.0.0-M4 milestone release) for getting started so you do not need to migrate from 1.x to 2.x in the future. NiFi 2.x has a load of enhancements including a great new user interface and custom extensions using python. Additional FYI: NiFi can be extended with custom java or python code to do anything your team needs and is capable of coding. Those extensions called custom nars provide ultimate flexibility, but the vast majority of the time the unmodified NiFi release will fully support your needs without any custom code.
