Converting an Oldrim Mod to SSE

[CryptHammer]

I would like to convert an oldrim mod to SSE, called "Riding Styles".  I've never converted a mod before and have no experience creating mods.  I've done a good bit of reading online and have been able to convert the esm that comes with the original mod to an esp so I could save it as an sse mod, then converted it back to an esm (using SSEEdit and CK).  I've converted all of the animations to SSE animations using the "converttoskyrimse.bat" program from the Nexus site.  In his comments, he says that this doesn't work with behavior files, and someone else commented that they would be regenerating the behavior files using the FNIS for Modders tool.  All that to say, how do I convert behavior files using FNIS for Modders?  Is this something that is far too complex for a noob like me?  I would like to clarify that I currently have a working Skyrim SE build and would like to keep it that way, so if there's some possibility that I'm going to totally screw up my installation and have to start from scratch, I'd rather not do it.  Thanks for your help.
