Dear Aspirant,

Changing of category is allowed by NTA, however you'll have to fill the application form as a new candidate. Since in both the exams your categories are different, so you won't be treated as same person, but different. If you have valid proof of belonging to OBC category, then fill in a new form.
Hope this helps.
