As a seasoned full-stack developer with a strong focus on eCommerce and MySQL, I'm excited to offer my proven expertise in upgrading Prestashop stores for your project. With over 12 years in the field, I have successfully completed numerous version upgrades - including migratating data, resolving module conflicts, and handling theme rewrites - which are crucial for ensuring a seamless transition between major versions like Prestashop 1.7.x to 9.x. One of my core strengths is my deep understanding of the Prestashop ecosystem and its different modules and themes. Moreover, I am comfortable using Git version control, Composer-based installations and working with overrides - skills that you have highlighted as being critical for this project. Having spent years working hands-on, I've developed an instinctive ability to anticipate and preemptively address potential roadblocks which might disrupt your existing system such as template conflicts or broken overrides after the upgrade.

✨PRESTASHOP 1.7 → 9.x UPGRADE — SAFE, SEAMLESS & ZERO DATA LOSS ✨ Hi! I’m Nupur — I specialise in complex PrestaShop upgrades and migrations, ensuring everything works perfectly post-upgrade without breaking your store’s functionality. Upgrading from 1.7.8.6 to 9.x is a major version jump, and doing it without data loss or broken modules requires a structured, expert approach — which I’m fully confident in delivering. Relevant Experience: I’ve handled major PrestaShop upgrades, including cases where: ➡️ Legacy modules were incompatible and required replacement or custom fixes ➡️ Themes needed partial or full restructuring due to override conflicts ➡️ Custom code had to be adapted for newer architecture (Symfony-based changes) Quick Questions: 1️⃣ Are you using a custom theme or modified default theme? 2️⃣ Any critical third-party modules (payment/shipping) I should review first? 3️⃣ Is your store single or multistore setup? ➤ I focus on zero-risk upgrades with full functionality retention ➤ Clean, documented process so you’re never left guessing ➤ Post-launch support included for stability I understand you only want experienced developers for this upgrade — and I’m confident I can deliver a smooth, production-safe transition. Ready to start immediately and ensure your store runs flawlessly on PrestaShop 9.x. — Nupur

Hello, I understand you need a full PrestaShop upgrade from 1.7.8.6 to 9.x with zero data loss and full preservation of all modules, customizations, and storefront functionality. I will start by creating a complete staging environment (files + database clone) to ensure your live store remains fully safe during the process. From there, I will handle a structured upgrade path to PrestaShop 9.1, carefully managing backward compatibility issues, core changes, and dependency updates. All modules and theme components will be audited and updated or replaced as needed to ensure full compatibility with the latest version. I will also review and refactor any custom overrides or modifications to align with PrestaShop 9 architecture while preserving existing functionality. Data migration will be fully validated, including products, customers, orders, SEO URLs, multistore configurations, translations, and payment/shipping integrations. After upgrade, I will perform full end-to-end testing of checkout, catalog, order flow, email notifications, and admin operations to ensure everything behaves correctly. Before deployment, I will provide a rollback-ready backup plan. Once validated, I will deploy the upgraded store with minimal downtime and ensure post-launch stability with a bug-fix support window. Deliverables include the fully upgraded PrestaShop 9.1 store, a detailed change log (modules, overrides, fixes), and documentation of the upgrade process. Thanks, Asif

@temoberishvili

Hello! I’ve carefully read your project description about upgrading your Prestashop store from 1.7.8.6 to the latest 9.x version, and I’m confident I can help you achieve this without any data loss. With over 10 years of experience in PHP, eCommerce, and web development, I have the skills to ensure a smooth upgrade process while maintaining the integrity of your live store. To better understand your needs, could you please clarify the following questions? 1. Are there any specific customizations or modules in your current setup that need special attention during the upgrade? 2. What is your timeline for this upgrade, and do you have a preferred period for minimal downtime? I’ve successfully completed similar projects, such as upgrading an eCommerce site that integrated custom payment solutions and enhancing another shop's performance with optimized backend processes. I focus on delivering reliable solutions tailored to my clients' needs. I’m genuinely excited about the opportunity to work together on this project and ensure your store is up-to-date and secure. Looking forward to your response! Best regards.

Hello, I will run the PrestaShop 1.7.8.6 to 9.1 upgrade on a staging clone, migrate every module and theme, verify products/orders/customers/SEO URLs/translations, regression-test front and back office (checkout, payments, shipping, stock, emails, reports), then push to production with a tagged rollback snapshot. Have completed a 1.7 to 9 migration already and can share the reference in chat. On a 1.7 to 9 jump, the real work is pre-flight: PS 9 dropped most legacy admin controllers and bumped to PHP 8.1+, so 1.7 modules with legacy controllers or PHP 7 syntax need rewriting or replacement before the upgrade script completes. I map a per-module compatibility matrix on staging first, then run the upgrade with override-by-override theme migration, payment-gateway smoke tests, and a tagged rollback snapshot ready before cutover. Questions: 1) Module list ready, and how many are custom-coded versus marketplace? 2) Theme: paid/marketplace, custom build, or heavily overridden default? Looking forward to your response. Best regards, Faizan

Hi, As per my understanding: You need a zero-risk upgrade of your live PrestaShop store from 1.7.8.6 to 9.1, ensuring all modules, customizations, theme behavior, and complete data integrity remain intact, with full testing and minimal downtime. Implementation approach: I will first clone your store into a secure staging environment with full database backup. Then I will audit all modules, overrides, and theme customizations to identify compatibility gaps between 1.7 and 9.x. The upgrade will be executed using a Composer-based approach where applicable, ensuring clean dependency handling. I will update or replace incompatible modules, refactor overrides, and adjust theme templates for 9.x architecture. All data (products, customers, orders, SEO, multistore, translations) will be validated post-migration. Extensive testing will cover checkout, payment, shipping, emails, and admin workflows. After resolving conflicts, I will deploy to production with a rollback plan and near-zero downtime. A detailed report and post-launch support will be included. A few quick questions: 1. How many third-party modules and custom overrides are currently active? 2. Is your theme custom-built or purchased from a marketplace? 3. Which payment and shipping integrations are critical? 4. Do you currently use multistore or multiple languages?

@priyanshug777

Hi, I’ve completed PrestaShop 1.7 → 9 upgrades for stores with custom modules, overrides, and heavily modified themes, ensuring zero data loss and full feature continuity. My approach: 1. Staging & safety Full clone of files + database Work only on staging (Git-based workflow if available) 2. Controlled upgrade (not one-click) Pre-audit of modules, overrides, and theme customizations Step-by-step upgrade to 9.x handling breaking changes 3. Compatibility fixes Update or replace incompatible modules Refactor/remove broken overrides Adjust theme templates for PrestaShop 9 (Twig/Symfony changes if needed) 4. Data integrity Preserve all data: products, combinations, customers, orders, SEO URLs, translations, multistore No duplicates or losses 5. Full QA on staging Checkout + payment gateways Shipping calculations Emails, reports, customer accounts Fix all conflicts before go-live 6. Deployment + rollback Scheduled deployment with minimal downtime Full backup + rollback-ready plan Challenges I’ve handled: Fixing override conflicts after upgrade Replacing outdated modules safely Resolving payment/shipping issues post-upgrade Adapting custom themes to new architecture Deliverables: Fully upgraded PrestaShop 9.x store Detailed list of module/theme updates + code changes Post-launch support Timeline: 3–6 days depending on complexity I focus on stable, clean upgrades with zero surprises. Ready to start immediately

@Andyloredo

Successfully navigating the backward-compatibility changes inherent in a Prestashop 1.7 to 9.x upgrade requires careful module and theme management. I've previously handled similar migrations for eCommerce clients, specifically addressing module conflicts and theme rewrites to maintain full functionality post-upgrade – a key requirement for your project. I'll prioritize creating a safe staging environment and meticulously verifying data integrity, including SEO URLs and multistore settings, as you’ve outlined. Given the 7-day timeline, I anticipate completing the upgrade, testing, and initial conflict resolution within 5-6 days, with a buffer for unexpected issues and a clear rollback plan ready.
