The attached document below is a step-by-step guide for upgrading IIQ 8.0 to IIQ 8.1. Also, please note that the guide goes into detail how to apply patch 8.1p4. I tried to make it as simple as possible and provided screenshots to help with the upgrade process.
@Rupadantuluri1 It's actually just the same process. You are 2 versions behind so you will first have to upgrade to 8.3 following the steps and then do the same thing from 8.3 to 8.4.
