3. How to Migrate Your Store from CS-Cart to
PrestaShop
The choice of a shopping cart depends on many factors – the type and the size of your
business, the time you can dedicate to it, the money you are ready to spend on
ecommerce software, your location, your technical and programming skills and your
personal preferences. You may pick out a definite e-commerce platform because of
some of its features or you may simply like its design.
If, for some reason or other, you are not satisfied with CS-Cart and you would like to
migrate to PrestaShop, you can do it effortlessly, quickly and painlessly with
Cart2Cart, an automated shopping cart migration service.
PrestaShop is a flexible, feature-rich and user-friendly e-commerce solution.
Currently it powers more than 100,000 online stores. PrestaShop is free – a
significant advantage over CS-Cart. Also it’s open-source, which means you can
make your own modifications to its source code.
If you have made the firm decision to migrate from CS-Cart to PrestaShop, Cart2Cart
service will help you do it without difficulty.
You will need to register an account or sign in from your existing Facebook or
Google profile. At the moment you start the migration, both your stores must be
accessible online. Calculate how much your migration will cost with Migration
Estimator.

4. You don’t need much technical knowledge to perform the migration. Just follow the

1. Source Cart Setup
