I’m currently running PrestaShop 1.7.1.1 and want to move to the most recent stable release that won’t break my store. There are custom core modifications in place, but I do have complete file and database backups ready. What I need from you: • Audit the existing installation, including any overridden core files, to determine the highest version we can safely reach. • Map out the upgrade path (staging copy, incremental jumps, or direct upgrade) and explain the risks for each step. • Execute the upgrade on a staging environment first, making sure every installed module remains operational—especially payment, shipping, and product-handling extensions. • Reapply or refactor my custom core tweaks where necessary so nothing is lost. • Once everything passes testing, migrate the updated codebase and database to production and validate frontend, backend, and checkout flow. • Provide a concise post-upgrade report with a rollback plan and tips for future updates. You’re free to use the official 1-Click Upgrade module, manual FTP/MySQL methods, or another proven workflow; the goal is a smooth transition with zero downtime to customers. If you have recent experience upgrading PrestaShop 1.7.x stores that contain custom edits, let me know your approach and timeframe.

Hello, I will audit your PrestaShop 1.7.1.1 install to determine the highest stable version you can safely reach, given your custom core tweaks and full backups. I will map a practical upgrade path—staging first, with incremental jumps or a direct upgrade where safe—and spell out the risks at each step. I will perform the upgrade on a staging site, keeping payments, shipping, and product management modules working, then reapply or refactor your custom tweaks so nothing is lost. After thorough testing, I will migrate the updated codebase and database to production and validate frontend, backend, and checkout flow. I will deliver a concise post-upgrade report with a rollback plan and tips for future updates. I’m happy to use the official 1-Click Upgrade or a manual workflow based on what best preserves your setup and minimizes downtime. What is your target latest stable PrestaShop version for this upgrade? Do you have a staging environment that mirrors production and can you provide test credentials for payment and shipping modules? How many custom core tweaks are in place, and can you share a list of overridden files or code changes? What is your downtime tolerance and preferred upgrade sequence: staged upgrades or a direct upgrade if safe? Would you like a detailed post-upgrade report with rollback steps and a plan for ongoing updates? Best regards,

Ciao, sono Rafa, sviluppatore con esperienza concreta in aggiornamenti di PrestaShop, soprattutto su versioni 1.7.x con modifiche al core e moduli personalizzati. Posso occuparmi dell'intero processo di upgrade partendo da un audit completo dell’installazione attuale (1.7.1.1), analizzando file sovrascritti, override, moduli critici (pagamento, spedizione, gestione prodotti) e valutando quale sia la versione stabile più alta raggiungibile senza rompere nulla. Ti propongo un piano di aggiornamento chiaro: – Creo un ambiente di staging dove testare ogni step, anche tramite aggiornamenti incrementali se necessario. – Riapplico o riscrivo le modifiche custom per garantire compatibilità futura. – Una volta che tutto è testato e funzionante, eseguo la migrazione in produzione minimizzando il downtime. – Concludo con un report dettagliato: cosa è stato fatto, cosa è stato adattato, e come affrontare i prossimi aggiornamenti in modo sicuro (incluso un piano di rollback). Lavoro con 1-Click Upgrade solo dove è realmente stabile, altrimenti uso approcci manuali (FTP, dump SQL, merging selettivo). Contattami per discutere accessi, tempi stimati e procedere con la prima analisi.
