Continuing to run an old version of WooCommerce is a mistake. WooCommerce for WordPress is easy to update and updates can provide important security and functional updates. We highly recommend doing your updates on a staging site in all cases to first test that everything functions correctly. When you have set up your site on a staging site, simply go to your plugins and click Update Now if you need to update WooCommerce. The more customized your site, the more complex this can be. So, don’t hesitate to get a pro to help you and save you the hassle and time.
