Well, current website uses older version of wordpress so what I really want to do is delete everything there is on the server and start from scratch but I want to have a backup of existing site in case something goes wrong or in case client changes his mind.
It is not just a redesign, it is a lot of new content, widgets and plugins which are already activated and setup on my localhost so I really don’t want to do that again.
As I mentioned I want to just move new wordpress with new theme to a server using Duplicator and I will manually create a SQL database in cPanel.
I will use this tutorial: https://www.youtube.com/watch?v=86b7s5xtdP8
So my question here really is: Can I just follow steps in this tutorial no matter that there is already a wordpress instalation on my server or I need to delete all the content from the server for this to work?
