CodeIgniter 3 to Django 4.2

I have a fairly big CodeIgniter3 codebase and now I want it migrated to Django 4.2.
Is it possible to create the same models in Django retaining the table structure ?

firstName = models.CharField(max_length=100, db_column='first_name')

How do I got about migration of users table ?

Hi, I was doing our RnD for migration from Codeigniter3 to Django, may I know if I can able to get some help from you please, as I saw that you successfully did it, how I can start?
