I’m ready to move my current Prestashop store (version 1.7.8.6) to the latest Prestashop 9 release and need an experienced developer to handle the entire process smoothly. Key goals • Carry out a clean, secure upgrade from 1.7.8.6 to 9 without disrupting day-to-day operations. • Preserve the existing storefront look-and-feel, catalogue, customer data, orders and any modules that must stay active. • Identify and resolve any compatibility issues that arise from third-party modules or custom tweaks. • Validate that core functionality—checkout, payments, shipping, back-office reporting—works exactly as before (or better). • Deploy the upgraded store to production only after thorough staging-site testing. What I expect from you 1. Full backup and rollback plan before you touch the live store. 2. A staging copy where you perform the upgrade, test and fix issues. 3. Clear documentation of steps taken, files modified and modules updated or replaced. 4. Post-upgrade QA: performance checks, security review, responsive layout testing on major browsers/devices. 5. Seamless switchover to the live site with minimal downtime. Nice to have • Recommendations on performance tuning for Prestashop 9. • Guidance on new features we can safely enable to future-proof the shop. If you’ve successfully upgraded Prestashop stores of similar size, please share a brief outline or links. Let’s keep the transition painless for our customers and staff while ensuring we benefit from everything Prestashop 9 offers.
