I would like to create my own persona(s) for my research. While due to some limitations, I don't do any formal user interview or observations myself. What I have as resources are the user research which have been done by other research team in the company. I have currently four different sources of user research materials. Mostly, they did user interviews and obeservation, others they did usability testing for one perticular product following certain kind of scenario.

My objective of this research is to identify the users' expectations, their pain points and their common points.

Could you give me some advices about how can I use these existing research?

*The exisiting reserach focused on the similar user types with mine. Therefore, I think that I could reuse their raw data to re-analyze and construct my persona(s)
