Upgrade my Wordpress website from PHP 7.4 to PHP 8.3.

I need to update my Wordpress website from PHP 7.4 to PHP 8.3. I am using Divi 4 theme a Woo commerce store - just 28 items download digital movies. You need to set up a local staging site to test the update - my hosting server is Mocha and PHP versions only run site wide not on staging sites - so my live website would be affected. I am fine with updating or changing any plugins that cause conflict - I run less than 10 plugins. You can see the site at emptymindfilms.com
