Introduction: Modernizing for Tomorrow with WAO Group


Addler, a prominent player in the manufacturing sector, had long relied on Odoo 10 as the backbone of their enterprise resource planning (ERP) operations. While Odoo 10 served its purpose, the rapid advancements in business technology and the significant feature enhancements in newer Odoo versions meant Addler was operating with an increasingly outdated system. Recognising the need for a robust, future-proof ERP solution, Addler partnered with WAO Group to undertake a critical and complex upgrade from Odoo version 10 to the cutting-edge Odoo version 18.


At WAO Group, we pride ourselves on being expert Odoo Implementation Partners and Odoo Migration Specialists dedicated to transforming businesses through seamless ERP solutions. This case study highlights our commitment to excellence and our team's unparalleled skill in navigating even the most challenging Odoo Upgrade Projects.

The Challenge: Bridging a Generational Gap in Odoo

The Challenge: Bridging a Generational Gap in Odoo


The leap from Odoo version 10 to version 18 is not merely an upgrade; it's a monumental Odoo ERP System Transformation. This significant version jump (eight major releases) presented a unique set of challenges:


1. Legacy Plugin Dependency:

Addler's Odoo v10 instance was heavily customised with numerous old, bespoke plugins and modules. These were critical to their daily operations but were incompatible with Odoo 18. Our task was to either Upgrade These Custom Odoo Modules to function with the new version or identify if their functionality had been integrated natively into Odoo 18, allowing for their removal.

2. Data Integrity at Risk:

Migrating years of critical business data across such a vast version gap posed a substantial risk to data integrity. Ensuring every record, transaction, and configuration was accurately transferred without loss or corruption was paramount.

3. Upskilling the Workforce:  

Addler's team was deeply familiar with Odoo 10. The transition to Odoo 18 required comprehensive Odoo training to familiarise them with the new interface, workflows, and functionalities, ensuring a smooth adoption.

4. Leveraging New Features:  

Odoo 18 boasts a wealth of new features, performance improvements, and enhanced usability. The challenge was not just to upgrade the system but to strategically assist Addler in taking full advantage of these capabilities to drive efficiency and growth.

Our approach to Addler's Odoo v10 to v18 Migration was multi-faceted, leveraging our deep expertise in Odoo Development and ERP System Upgrades:


1. In-depth Discovery & Strategic Planning:  

Our team began with a meticulous analysis of Addler's existing Odoo 10 setup, mapping all customisations, workflows, and data structures. This allowed us to formulate a precise Odoo Upgrade Strategy, identifying which legacy plugins required custom Odoo Module Migration and which could be replaced by native Odoo 18 features.

2. Expert Custom Module Re-engineering:  

This was a cornerstone of the project. Our seasoned Odoo Developers meticulously re-engineered essential legacy plugins, adapting their codebases to be fully compatible and performant within the Odoo 18 environment. For functionalities now native to Odoo 18, we guided Addler on how to leverage these built-in capabilities, streamlining their system and reducing reliance on external modules. This showcased our ability to not just migrate, but to optimise and modernise.

3. Unwavering Data Integrity Assurance:  

We implemented a rigorous Data Migration protocol, utilising advanced tools and multiple validation checks to ensure zero data loss and complete accuracy during the transfer process. Our team meticulously verified the integrity of all historical data, providing Addler with complete confidence in their new system.

4. Comprehensive User Upskilling & Training:   

Recognising the importance of user adoption, WAO Group designed and delivered tailored Odoo 18 Training Programs for Addler's team. These hands-on sessions covered new interface elements, updated workflows, and how to utilise the advanced features of Odoo 18, empowering their staff to maximise the system's potential from day one.

5. Strategic Feature Optimisation:  

Beyond the technical upgrade, our consultants worked closely with Addler to identify opportunities to leverage Odoo 18's new functionalities – from enhanced reporting and automation to improved user experience – ensuring their ERP System truly supported their evolving business needs.
