What must be checked before upgrade

Estatik 4.0 is a major version that contains significant changes and new functionality. That is why we strongly recommend before upgrade to double-check the following:

1. You have a full backup of your website. Thus you can roll back anytime to your initial website version if something goes wrong.

2. Your Estatik version is not customized. If you do have some code modifications, you will lose your custom changes.
