9.2.1 Upgrade to 9.6
CSM/CAM Version : CSM 9.21

Hello All, My company is looking into upgrading from CSM 9.2.1 to 9.6 has anyone upgraded from 9.2.1? I was trying to get some feedback on any issues you all might have ran into during and after the upgrade. I would appreciate any suggestions good or bad I'll take it! 

 We inherited our Cherwell so we currently have tons of layering on our Incident BO, my fear is if we upgrade something is going to break due to all the layering of fields on that BO.  Check out the layering below.
