Migrate Odoo 15 to 19
Last updated: February 2026
Migrating Odoo Community Edition from version 15 to 19 involves 999 model changes, 97 module merges, and 159 field renames. OCU automates this entire process — upload your database backup and download a production-ready database running Odoo 19.
What changes
Between Odoo 15 and 19: 166 model renames, 828 constraint changes, and 159 field renames across 999 affected models.
- Four-step migration, one upload. Chains 15 to 16 to 17 to 18 to 19 into a single operation — the longest supported path, covering five major Odoo versions.
- 999 model changes across 4 versions. 166 model renames, 97 module merges, 159 field renames, 828 constraint changes.
- Full architectural modernization. From coupon.program to loyalty.program, from mail.channel to discuss.channel, from ir_property to JSONB, from procurement.group to stock.reference.
Migration path
This is a 4-step migration handled automatically. You upload a version 15 backup and download a version 19 result — no intermediate steps required.
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 across all 4 steps.
- Download your upgraded backup, ready for Odoo 19.
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. This 4-step migration costs the same as a single-step one.
Frequently asked questions
- Can I really migrate from Odoo 15 all the way to 19?
- Yes. OCU chains four migration steps (15 to 16 to 17 to 18 to 19) into a single operation. You upload a v15 backup and download a v19 result.
- Why is Odoo 15 to 19 the longest supported path?
- Odoo Community 15 reached end of life in October 2024. Rather than migrating one version at a time, OCU chains all four steps so you land directly on the latest supported version.
