How can I move my website up one level?

[PS_Dude]

I had originally created my website under a subdirectory <www.domain.com>/ws to not interfere with a wordpress site that was there previously, then when I finished developing my prestashop site, I just redirected from the home page to the ws subdirectory.  All works fine, but now it seems I can't get SSL working because of the redirect (so says my web host).  I have a bunch of custom code which will be very difficult to re-implement, so is there a *safe* way to move the site up one level? 

And can I just save the whole file/directory structure and put it back in case of any issue?

Thanks.

clean out destination 

copy files to root

access back office or via  phpmyadmin set base uri from ws to /

rename .htaccess to .htaccess_ws

access back office

preferences-->seo & urls---scroll down...disable then enable friendly url to regenerate .htaccess

clear cache via performance page
