"Will we lose data?" is the first question every business asks before an Odoo upgrade. It is the right question. Here is the process we use to make sure the answer is always no.
Why migrations go wrong
Most failed migrations share the same causes: skipping a proper assessment, testing on production, ignoring custom module compatibility, or cutting over without a rollback plan. Each is avoidable with discipline.
Our five-phase process
1. Assess before you touch anything
We inventory every custom module, integration and configuration, then check each against the target version for deprecated APIs and breaking changes. This produces a compatibility report and a realistic timeline.
2. Always stage first
Production is never the place to experiment. We migrate a full copy of your database in a staging environment, so issues surface safely, long before go-live.
3. Port the customisations
This is the hard part. Standard data migrates with Odoo's own tools, but custom modules must be reviewed, refactored and tested. Integrations to payment, shipping, biometric or eCommerce systems often need targeted fixes.
4. Validate with real users
We run user acceptance testing on real workflows and real data. If a flow does not behave exactly as before (or better), it is not done.
5. Cut over with a safety net
Go-live happens with full backups and a rollback-safe plan. If anything unexpected appears, we can revert cleanly. In practice, careful preparation means cutover is the calmest part of the project.
The bottom line
Zero data loss is not luck. It is the result of assessing properly, staging everything, respecting your customisations and never cutting over without a way back. That is how an upgrade becomes routine instead of risky.
