A successful Odoo migration is not just about moving data. It's a project in its own right, where the costliest issues are often the ones you didn't anticipate.
The known challenges: compatibility of custom modules with the new version, the quality and cleaning of the data to migrate, user training, and managing downtime during the switch.
The lesser-known challenges: third-party modules (OCA or paid) that lag behind versions, custom automations and reports to rebuild, subtle behavior changes between versions, and the technical debt left by poorly documented customizations.
At Cetelex, we always start with a full audit before any migration: module inventory, mapping of customizations and testing on a staging environment. The result: a controlled switch, with no bad surprises and no business interruption.
