Tinkerpop Gremlin upgrade path (3.4.10 - 3.6.5)

Question

I have to upgrade AWS Neptune Engine version to 1.2.1.0. The current Tinkerpop gremlin version (as a client) is 3.4.10. Now, Thought I have already upgraded the Neptune server version which is still working good with client 3.4.10. But the recommended Max Tinkerpop version is 3.6.5 (ref: https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-client.html). So, here comes my challenge. I have a huge leap of version upgrade path and all I am looking for some help/assistence to know the required changes in terms of libraries/JARs upgrade. E.g: Tinkerpop 3.6.5 requires HGraphDB version 3.2.0. Similarly, I want to know what other libraries are required to be upgraded. Of course, for other dependent libraries to upgrade or introduce freshly, it depends on whether I use it already in my other Application or not.
