Hello everyone,
I have already developed website in codeigniter 4.0.1. Now I want to upgrade it to 4.0.3. How can I do it without losing my most of work. I know some functionality can break but that I can re-code it.

You just need to copy over the system folder, but this depends on if there where
any changes to the app folder if there where then you also need to copy over the
app folder which means you need to backup you app folder then re-create it for
your project.
