Migrate Odoo 17 to 18
Last updated: February 2026
Migrating Odoo Community Edition from version 17 to 18 involves 193 model changes, 25 module merges, and 31 field renames. OCU automates this entire process — upload your database backup and download a production-ready database running Odoo 18.
What changes
Between Odoo 17 and 18: 14 model renames, 116 constraint changes, and 31 field renames across 193 affected models.
- ir_property to JSONB conversion. Company-dependent fields restructured from ir_property table to native JSONB columns.
- Product configurator merged into sales. sale_product_configurator folds into core sale module.
- Cleanest migration path. Zero stale expressions detected — the safest and most reliable upgrade path.
How it works
- Upload your .zip, .sql, or .dump backup. We auto-detect the source version.
- Migrate. We handle schema changes, module merges, field renames, and data migration.
- Download your upgraded backup, ready for Odoo 18.
Pricing
Test migrations are free and unlimited. The output is neutralized (emails disabled, crons off) so it is safe to explore but not for production use.
Production migrations cost one credit (99 EUR), charged only when the migration completes successfully.
