Why redesign or migrate your PrestaShop B2B store?

In a constantly evolving digital environment, an outdated PrestaShop store becomes a hindrance: performance loss, incompatibility with recent modules, security vulnerabilities, difficulties interconnecting with your IS. In B2B, where volumes are often high and expectations very specific (complex pricing, quotes, ERP, customer profiles...), an update or redesign is not an option — it's a strategic lever.

At GDN, we turn these obstacles into opportunities: modernizing your PrestaShop store is the opportunity to start fresh with a healthy, modern, and scalable foundation. Our mission: putting your tools back at the service of your teams, your customers, and your business ambitions.

Update or migration: what's the difference?

The update is a version upgrade within the same generation (e.g., 1.7.6 → 1.7.8), with limited impact on modules or theme if they are compatible.

Migration, however, involves changing the foundation (e.g., from 1.6 to 8.0), often with breaks in modules, back-office, or even business logic.

Why update PrestaShop B2B? The advantages of a controlled version upgrade are numerous:

  • Activation of new features: multi-warehouse management, personalized customer profiles, user roles, extended ERP connectors
  • Performance improvements: better PHP 8+ optimizations, faster loading, better load handling
  • Enhanced security: correction of known vulnerabilities, data protection, GDPR compliance
  • Technological compatibility: with new browsers, modules, data formats, APIs
  • Growth preparation: better architecture for PIM, CRM, mobile or headless interconnections

Redesigning your PrestaShop store: when to start from scratch?

In some cases, a simple migration is not enough. We recommend a complete redesign when:

  • The current architecture is too unstable or overloaded
  • The theme is outdated or not responsive
  • You want to fully leverage the new features of the latest version of PrestaShop
  • Your IS has evolved (new PIM, new pricing logic, new user roles)

The redesign then allows rebuilding a clean, scalable foundation perfectly aligned with your business challenges. It's often accompanied by a UX/UI redesign, new product logic, or segmentation by customer entity.

Our method to migrate or redesign your B2B store

We work with method, transparency, and deep knowledge of B2B e-commerce challenges.

1. Existing system audit

  • Complete review of current version, installed modules, themes, customizations
  • Analysis of connectors (ERP, PIM, CRM)
  • Identification of critical or incompatible modules
  • Detection of overrides, overloads, and hacks

2. Migration plan and backup

  • Complete environment backup (files, DB, media, modules)
  • Writing a migration or redesign plan with precise milestones
  • Technology choice: partial migration or complete redesign, data recovery

3. Controlled version upgrade / redesign

  • Setting up a test environment
  • PrestaShop core migration + module adaptation
  • Refactoring or rewriting customizations if necessary
  • Theme adaptation if needed (redesign or compatibility)

4. Business-oriented functional testing

  • B2B order tunnel verification
  • Testing of ERP exports, specific prices, tax rules, quote modules
  • Recovery of histories (customers, orders, catalogs, attachments)

5. Secure production deployment

  • Deployment without business interruption if possible
  • Active monitoring during the 48 to 72 hours following go-live
