Renamening already created site

Hello i have my old shop at public_html/myshop and i've installed opencart like this public_html/newshoptest
Now i want to paste any information from my old shop to my new shop and when it's ready to rename the folder newshop to myshop so that my domain can work with it, where and what in the files must i do in order to change the folder name that contains my new opencart site ? And the site to function correctly ?

Changing the path in /config.php and admin/config.php does the trick
