Project Overview<\/h1>\n

This engagement delivered a risk-free, staged upgrade path from Dolibarr v12 to v18 while safeguarding production data and migrating every customization into the supported \/custom\/<\/code> structure. The upgrade followed a strict “Backup First \u2014 Staging Only \u2014 Future-Proofed” methodology to eliminate downtime and simplify future maintenance.<\/p>\n

Core Principles<\/h3>\n
    \n
  • Backup First<\/strong> \u2014 Full recovery options at every step (database + filesystem + off-site retention).<\/li>\n
  • Staging Only<\/strong> \u2014 All work performed on a private clone with zero production impact until go-live.<\/li>\n
  • Future-Proofed<\/strong> \u2014 All custom code migrated into \/custom\/<\/code> so future Dolibarr upgrades are seamless.<\/li>\n<\/ul>\n<\/section>\n
    \n

    Step-by-Step Plan (Executed)<\/h2>\n

    1. Assessment & Full Backup (Days 1\u20132)<\/h3>\n
      \n
    • Confirmed compatibility (PHP 8.1+, MySQL\/MariaDB 10.5+).<\/li>\n
    • Created complete backups: mysqldump<\/code> database export, full filesystem archive including conf.php<\/code>, documents\/<\/code>, and all custom code.<\/li>\n
    • Stored backups securely off-site with 30-day retention.<\/li>\n
    • Performed a customization audit to locate modifications in core, external folders, and existing \/custom\/<\/code>.<\/li>\n<\/ul>\n

      2. Staging Setup & Upgrade (Days 3\u20135)<\/h3>\n
        \n
      • Cloned production into a private staging server.<\/li>\n
      • Downloaded and installed Dolibarr v18.0.x on staging.<\/li>\n
      • Merged files carefully: replaced core, preserved conf.php<\/code>, documents\/<\/code>, and custom code.<\/li>\n
      • Ran the official upgrade wizard (\/install\/<\/code>) and verified database migration.<\/li>\n
      • Performed initial validation: user login, core modules, and navigation checks.<\/li>\n<\/ul>\n

        3. Customization Migration & Testing (Days 6\u201314)<\/h3>\n
          \n
        • Preserved existing \/custom\/<\/code> content; refactored any customizations found in core files or external folders and relocated them into \/custom\/modules\/<\/code>, \/custom\/pdf\/<\/code>, etc.<\/li>\n
        • Updated third-party modules to v18-compatible versions.<\/li>\n
        • Executed rigorous testing:\n
            \n
          • Replicated all client workflows (as shown in the provided video).<\/li>\n
          • Performed end-to-end UAT with the client’s key users via shared staging access.<\/li>\n
          • Logged, fixed, and documented all issues.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

            4. Production Go-Live (Days 15\u201318)<\/h3>\n
              \n
            • Scheduled a 30\u201360 minute off-peak maintenance window.<\/li>\n
            • Applied upgrade and customization migration on production.<\/li>\n
            • Cleared caches, locked the installer, and monitored logs for anomalies.<\/li>\n
            • Delivered updated documentation, a 1-hour training session, and provided 1-week post-launch support.<\/li>\n<\/ul>\n<\/section>\n
