I just took charge of a website made by another webmaster with Corona 1.2.
I’d like to update the theme to 1.6 version, and that’s why I purchased it again (the old webmaster doesn’t help me…).
However, I know there have been some customization (e.g. in header.php, and style.css) and I’m afraid that if I update the whole theme I can lose some customization.
Could you tell me if there are only some core files to change, moving from 1.2 to 1.6, so that I try to update only those files?
I don’t need to improve the website with any function, I simply want to have a newer version for security reasons.
