I need my current Odoo 14 Community Edition instance—with roughly four years of transactional history—migrated to Odoo 19 Enterprise Edition without losing a single record. Data accuracy is my top priority, so every partner, product, journal entry, attachment, and historical report must match exactly once the switch is complete. Beyond the core database, the job involves: • Porting a set of bespoke add-ons written in Python that extend standard Odoo functionality. • Re-creating all existing reports so they render identically (or better) in 19 EE. • Re-establishing live connections to my payment gateways, shipping services, and marketing tools. I expect a staged approach: first a cloned test upgrade where we can reconcile data and validate workflows, followed by a cut-over plan that keeps downtime to an absolute minimum. Full technical documentation and a brief hand-off session round out the deliverables. If you have proven experience moving large Odoo databases between Community and Enterprise editions, especially with custom code and multiple integrations, I’m ready to get started right away.
