I have an existing magento 126.96.36.199 site and I want to update the theme so its responsive. I cant seem to find any tutorials on this specific topic, unbelieveably. Assuming its not just as easy as installing a new theme and then activating it in the magento panel.
Im mostly a front end developer/graphic designer but I do have a decent grasp of where and what stuff is but Im certainly a novice still. Ive only worked on existing magento sites, never started one from scratch or updated the themes.
Have you read the official documentation already:
Also, here's another resource that comes in handy. In case you wish to add JS & CSS files in custom locations:
What Im trying to find out is whether there is an "easy" way to merge a new theme with an old theme without hitting every part of the site to adjust things after I switch over. From what Ive found out ( and it makes sense ) is there is not an easy way and you will end up retweaking the site to fit the new theme ... or am I searching poorly?
