Invoking make install will copy the provided .jwmrc to your home directory and therefore overwrite an existing file. Feel free to backup your existing file before:

cp ~/.jwmrc ~/.jwmrc.bak

And this theme for which jwm version is ??? I mean i don't want to accidentally outdate some options of my .jwmrc file by installing it

As you can see in the provided .jwmrc, this theme was developed for and tested with JWM 2.3:

<JWM>
   <!--
   TITLE:	Phono
   AUTHOR:	Christian Bettinger <https://github.com/cbettinger>
   JWM ver:	JWM 2.3
   -->
   ...
</JWM>

I would recommend to backup your .jwmrc as described above, then install the theme using make install and copy your specific configuration lines from your file .jwmrc.bak to .jwmrc.
