Advice on how to make a client patch with Kagero and Obaro Job

[Hadeszeus 15]

First of all I don't know if this post make sense since I really dunno how it works. I just notice it on my live server.

 

I'm using 2014 client with these 2 new jobs. The problem is the players who uses SMALL CLIENT files + 2012 RO Files. Their client CRASH since it doesn't support new jobs.
Can someone guide me what files should I need to add in my GRF to solve the issue of crashing with old RO? Or maybe you want to share yours.
