Update WordPress theme without losing customization

It is always recommended to update your WordPress theme to the latest version because it ensures the security and lets you access all the latest features.

However, when you update a Wordpress theme, the problem is you may lose all the tweaks you made to it. And, that’s the reason why WordPress experts always suggest you to use a child theme and make any tweaks in it rather than tweaking a parent theme.

 

That said, what if you already tweaked your current theme without using a child theme? If you don’t remember all the changes you made to the theme, how would you identify all the tweaks and replicate it to your latest version?

In this post, we’ll show you how to update your WordPress theme without losing any customization. We’re going to identify the tweaks you made into your current theme by comparing the current theme with the latest theme. Then, we’ll copy all the tweaks to the latest theme.
