I cannot install the updated theme as well. Error message:

 
<h1>Installing Theme from uploaded file: jevelin_2.1.2.V2.zip</h1>
Unpacking the package…

Installing the theme…

Destination folder already exists. /home/wp_jfwgnk/digi.vc/wp-content/themes/jevelin/

Theme install failed.

I am also wondering when installing this new update that has hopefully fixed my bugs will the content/links/formatting automatically switch over to the new theme downloaded version? Can you please advise how to easily migrate my currently active Jevelin theme to the recommended Jevelin Beta update
