Context

Odoo v17, v18, and v19 introduced significant frontend changes including OWL-based architecture, updated asset handling, and new website editor behavior. These changes improve performance and flexibility but create challenges for systems built on older versions. Businesses upgrading from Odoo v12–v16 often face broken views, incompatible JavaScript, and outdated themes. A structured frontend migration ensures compatibility, performance, and long-term maintainability.

Who this is for

We work best with teams who treat software as an operating system for the business, not a one-off project.

Good fit

Businesses upgrading from Odoo v12 to v16
Companies with heavily customized Odoo frontends
Teams facing frontend issues after Odoo upgrades
Organizations needing modern and responsive UI in Odoo

Not a fit

New Odoo implementations without legacy frontend code
Systems already fully compatible with v17+ frontend
Projects without frontend customization
Teams not planning version upgrades

The operating reality

Odoo upgrades fail when frontend code is not aligned with modern architecture.

Legacy frontend code built with jQuery and older APIs breaks when migrating to newer Odoo versions. Custom themes, widgets, and views become incompatible, leading to UI errors, slow performance, and missing functionality. Without proper migration, businesses face unstable interfaces, poor user experience, and increased technical debt that affects future upgrades.

How this is usually solved

Common approaches

Where it falls short

Common approaches

Direct upgrades without frontend refactoring
Patching broken views instead of full migration
Continuing use of deprecated JS and jQuery
Ignoring asset optimization and performance issues

Where it falls short

Broken UI components and widgets
Slow page performance
Inconsistent user experience
Higher cost for future upgrades
