We recently went through the same process. We upgraded our indexing service from 1.9.1 to 3.6.1. Unfortunately, the process is not as easy as you thought. Besides replacing the jar files. You also need to change your code to adopt to the new API. There are many changes, the most import parts are in IndexWriter, IndexReader, and IndexSearcher classes.
