Hi currently have wordpress 4.7 installed . I want to upgrade it 4.7.3 . But wthe problem is that in many of wordpress root folder we have other custom folder and files , that We don't want to lose .
I see the release archive https://codex.wordpress.org/Version_4.7.3 . It showed the List of Files Revised . So what we are planing to do is take each file individually and replace it with the new released file , for example take old wp-admin/js/common.js and replace it with new wp-admin/js/common.js . Is it possible ? .Is it a good method to update ? If i update this way my website is 100% update to new version .
