I am currently using a 1.3.6 Prestashop layout, and I would like to upgrade my Prestashop version to the latest 1.4.2 version.
This is a live Prestashop with 1,400 products. I need everything to be fully functional. All the products, and catalog to work.
Prestashop back office and front office should load slow or anything in this nature. I need the site to be optimized.
Only bid if you have experience with Prestashop, and you are confident you can perform this upgrade.
