Migration from Odoo 16 to Odoo 19 in Multi-Company Operations with High-Volume POS

At Borx Tech, we continue to lead complex digital transformation projects. One of the most challenging ones recently was the Migration from Odoo 16 to Odoo 19 for a multi-company operation with a presence in multiple states, which integrates retail, restaurants, convenience stores, and a high-demand POS ecosystem.

Project Background

The client was running Odoo 16 on an Odoo.sh architecture, including:

179 custom modules, tailored to specific business processes.
19 active companies10 of which have intensive operations.
High transaction volume in Points of Sale (PoS) with multiple simultaneous cash registers.
Broad product portfolio: food, beverages, fast-moving consumer goods (FMCG), including categories such as alcoholic beverages, snacks, dairy, and products from global brands like Nestlé.

This environment required a precise migration, with no margin for prolonged downtime or loss of operational integrity.

Key Challenges

The project's complexity was marked by several factors:

High customization: 179 modules meant reviewing compatibility, refactoring, and optimizing for Odoo 19.
Distributed operation: multiple states and companies with different accounting and operational rules.
High-volume PoS: Odoo 19 introduces changes in data loading, which directly impacts session opening.
True multi-company: financial consolidation, simultaneous operations, and cross-inventory control.

Migration Strategy

At Borx Tech, we designed a phased strategy to minimize risks:

🔍 Evaluación y Refactorización

Comprehensive audit of custom modules.
Identification of critical dependencies and elimination of technical debt.
Logic adjustment for compatibility with Odoo 19.

💻 Entorno de Staging Controlado

Iterative migration in staging environments on Odoo.sh.
Functional and technical validation with key users.
Specific PoS testing (performance, product loading, sessions).

⚙️ Optimización de PoS

Reduction of initial product loading (preload).
Hybrid strategy between local cache and dynamic search.
Adjustments to avoid bottlenecks at high-traffic cash registers.

🚀 Go-Live Controlado

Results

The migration to Odoo 19 allowed:

Better overall system performance, especially in concurrent operations.
Greater stability in PoS, even in high-volume scenarios.
Cleaner and more scalable architecture, reducing accumulated technical debt.
Solid foundation for growth, future integrations, and new functionalities.
