PrestaShop

PrestaShop is an open-source e-commerce platform used to build and operate online stores. It is primarily written in PHP and commonly runs with a relational database, a web server, and a PHP runtime. Its core provides a storefront, back-office administration, product catalog, inventory and order handling, customer accounts, promotions, tax and shipping configuration, payment integration, localization, and reporting. Store-specific behavior is commonly added through themes, modules, overrides, custom code, and connections to services such as payment providers, carriers, marketplaces, ERP systems, and marketing tools.

PrestaShop emerged as a self-hosted shopping-cart application aimed at merchants that wanted more control than hosted commerce products typically offered. Its early architecture centered on a PHP application with a template-based storefront and a module ecosystem. Over time, the project expanded its internationalization, catalog, multistore, API, and back-office capabilities, while its commercial ecosystem grew around paid modules, themes, hosting, support, and implementation services. Later development has progressively modernized parts of the administration interface and application architecture, but many long-running stores still contain code and extensions built for older conventions.

Migration planning must account for both business data and behavior distributed across the installation. Products, combinations or variants, categories, customers, addresses, orders, carts, stock, taxes, currencies, translations, customer groups, discounts, and content pages may all need mapping. Historical orders can be especially difficult because their totals, tax rules, shipping details, payment states, and product snapshots must remain meaningful after transfer. Password hashes are not always portable between platforms, so customer account migration may require a password-reset process. SEO preservation requires careful handling of product and category URLs, redirects, metadata, canonical behavior, language and shop context, and image paths. A PrestaShop store may be heavily customized through modules, theme changes, direct core edits, overrides, database modifications, and bespoke integrations. Modules can introduce their own tables, configuration records, hooks, scheduled jobs, files, and external dependencies, so a database export alone rarely captures the whole store. Moving into PrestaShop requires deciding whether existing workflows can use native features or need maintained modules or custom development. Moving away requires inventorying every module and integration, identifying the business rule it implements, and rebuilding or retiring it in the destination. Theme migration is usually a redesign or reimplementation rather than a direct conversion, since templates, hooks, assets, and front-end assumptions are platform-specific. Upgrade-related migrations within the PrestaShop ecosystem can also be complicated by obsolete themes, extensions that rely on older hooks or APIs, custom overrides, and differences in the back-office and template architecture. A staging migration, data reconciliation, redirect testing, payment and shipping tests, tax validation, performance testing, and a cutover plan for orders placed during the final sync are typically essential.
