Hi kidsdial4,
Thanks for reaching to us and appreciate your patience.
By default, all settings are same. However, I highly recommend you to take a complete backup of your site before proceeding.
Or create a devsite – also called a Staging platform where you can test issues, enable/disable features/plugins thus such changes will affect the main site. The below article will help you to create it:

Please refer to our detailed article https://xtemos.com/docs-topic/update-the-theme/
