Trying to add Enfold template to an existing site

Good morning.

I have the Enfold Theme and I am going to try to add it to my own business site.

The problem being I need this site up 24/7, so I have copied my site over to another domain and put it into maintenance mode.

Here is the question….

Once I have the site the way I want it can I use the “Export theme” feature to copy all the changes I have made over to the existing site?

Thanks for any help.

And keep up the great work on this “best ever” theme… IMHO
