Diagnosed chronic migraine due to daily debilitating pain . sometimes pain is extreme for up to six weeks my question is i occasionally get migraine with aura which feels different to daily pain ? how can it still be migraine if episodic different?

There are different types of migraines and a migraine with aura is a very classic presentation. You probably ought to see a headache specialist, usually a neurologist, to get these headaches properly diagnosed and then treated based on the diagnosis. Different migraine types have different treatment modalities and a headache specialist would know the best medication regimen for you. Good luck!

You would fit the category of Chronic Daily Migraine, and you should be treated with a preventative such as a CGRP inhibitor. Fluctuation of auras is not unusual, and events can vary from day to day. Crucial is to deal with the entire picture, but you need an experienced headache expert.
