I currently have a prestashop site ( v.220.127.116.11) and a brand new teplate that is v.18.104.22.168.
Is there a way to install the new theme..? do i have to update the already existed site and if yes can i updated it to 22.214.171.124 ?
Also does this change will have any effects at the website.? because we can't afford any mistakes and disabling the site is out of question.
Does this procedure has any effect at the database?
