The migration tool detects your current version, calculates the upgrade path (including multi-step migrations like 16→17→18→19), runs schema transformations, module migration, and data migration, and produces a ready-to-use backup.What's the difference between an Odoo upgrade and an Odoo update?An Odoo update applies patches within the same major version (e.g. 17.0.1 to 17.0.2) — usually bug fixes and security patches. An Odoo database upgrade moves your database to a new major version (e.g. Odoo 16 to 17), which involves schema changes, data migration, and module compatibility adjustments.Can I upgrade Odoo without losing my data?Yes. OCU preserves all your business data — customers, invoices, products, stock moves, and transactional records. We run integrity checks after every migration step. Your original backup is never modified.What is OpenUpgrade and does this tool use it?OpenUpgrade is an open-source community project that provides migration scripts for Odoo CE. OCU takes a different approach — we generate migration scripts by analyzing the structural differences between Odoo versions using AST parsing, then validate against real databases.What backup formats are supported?Standard Odoo backup formats: .zip (with filestore), .sql, and .dump files. These are the same files you get from the Odoo database manager or pg_dump.Which Odoo versions are supported?OCU supports Odoo Community Edition versions 16 through 19. Direct paths: 16 to 17, 17 to 18, 18 to 19. Multi-hop paths: 16 to 18, 16 to 19, 17 to 19 — all chained automatically.Does this work with Odoo Enterprise Edition?OCU is built for Odoo Community Edition. Enterprise databases require Odoo S.A.'s official migration service.How do I migrate my Odoo database to another server?OCU produces a standard Odoo backup file. After migration, restore it on your new server using the Odoo database manager or pg_restore.Security: Encrypted file handling. All uploaded data is automatically deleted after 72 hours.Visit ocu.winotto.com to get started.
