Additional resources to understand the value of an Odoo upgrade
Upgrading to a new Odoo version is more than just a technical update. Each release brings performance enhancements, new features, and critical security improvements.
To better understand the benefits of each version, we recommend reviewing the official Odoo release notes, which outline the latest updates, modules, and technical changes. These resources are essential to evaluate which version best suits your business.
These best practices help ensure your system remains compliant, resilient, and future-proof.

Challenges of an Odoo upgrade
and how to overcome them
Upgrading your ERP doesn't have to be stressful. With the right method, it's a chance to boost performance, security, and adoption.
1 The project is seen as long and expensive
An upgrade can feel like a heavy investment — both in time and resources — with no guaranteed ROI. Some companies hesitate, fearing the cost will outweigh the benefits.
- A clear, realistic planning: we define a detailed timeline with key milestones and deliverables to keep things on track.
- Transparent cost assessment: every upgrade begins with a technical and functional audit to estimate the budget precisely, identifying cost-saving opportunities such as simplification or removal of obsolete modules.
- Optimized developments: instead of migrating everything as-is, we analyze what can be streamlined or replaced by standard Odoo features, reducing long-term maintenance costs.
With efficient project management and clear expectations, the upgrade becomes a high-value investment — not a burden.
2 Ensuring compatibility of custom developments and modules
Some custom developments made on older versions may no longer be compatible with the new one. How can you ensure essential features remain functional?
- In-depth analysis of existing developments: we map and review all customizations to check their compatibility with the target Odoo version.
- Challenging unnecessary developments: we identify what can be replaced with standard Odoo features to reduce technical debt and improve maintainability.
- Rigorous testing: each critical feature is validated in a pre-production environment before going live, ensuring continuity without risk.
We don’t just migrate — we optimize your ERP to make it leaner, smarter, and easier to evolve.

Adoption by teams and organizational change
New interfaces and processes can create resistance, especially for teams used to a previous version. This can slow down go-live and affect productivity.
- Targeted training and user support: we involve teams early and tailor training sessions to different user profiles.
- Adoption strategy: we help you build internal communication plans and training materials to ensure a smooth change.
- Post-upgrade support: we stay available to assist users, answer questions, and quickly solve any friction points.
A successful upgrade also means your teams adopt the system confidently and effectively.
4Avoiding disruption and ensuring business continuity
Poorly planned upgrades can cause system downtime or data loss. How do you guarantee a seamless transition?
- Pre-production environment: we run all tests and validations in a safe staging environment to ensure no impact on your live system.
- Timing the go-live: we schedule upgrades during low-activity periods (evenings, weekends, or off-peak times).
- Phased rollout if needed: for complex projects, we can split the upgrade into stages with checkpoints at every phase.
- Reinforced post-upgrade support: our team monitors performance and remains available to ensure everything runs smoothly after go-live.
We deliver a well-planned upgrade, without business disruption and with peace of mind.
Our methodology for a
successful Odoo upgrade
Upgrading your Odoo system is a strategic project that needs to be secure, structured, and optimized to deliver real value.
At Eezee, we follow a proven 4-step methodology to ensure a smooth and reliable transition to the latest version while minimizing risks.
Every project is unique. That’s why we tailor our approach based on
the complexity of your current system, your business needs, and your strategic goals.
1. Audit & analysis – Understand before acting
Before starting any upgrade, we conduct an in-depth evaluation of your existing Odoo system to identify:
- Installed modules (standard and custom) and their compatibility with the target version.
- Specific developments: which ones are still used, which can be improved or removed
- Current business workflows and areas of improvement offered by the new version
- Any technical debt or risks associated with the migration
- A detailed diagnosis of the strengths and weaknesses of your current system
- A list of modules and features to migrate, adapt, or replace
- Strategic recommendations to rationalize the scope and maximize use of standard Odoo features
🎯 Goal: Anticipate challenges and structure a secure, well-defined upgrade plan.
2. Migration & re-engineering – Build a better ERP
This is when we start the actual technical and functional upgrade. But we don’t simply transfer your existing system — we use the opportunity to streamline and optimize.
Our approach includes:
- Migrating your codebase and data to the latest Odoo version
- Reworking and adapting custom developments to remove redundancies and prioritize standard Odoo functionalities
- Optimizing your database for better performance and stability
- Ensuring compliance with new technical and regulatory requirements
Your ERP should evolve with your business. Upgrading is a chance to simplify, modernize, and improve efficiency. We avoid blindly migrating everything and instead focus on reducing technical debt and building a system that’s sustainable.
🎯 Goal: Deliver a modernized, more efficient ERP that’s ready for the future.
3. Testing & validation – Guarantee system reliability
An ERP upgrade leaves no room for uncertainty. That’s why we implement extensive testing to ensure everything works perfectly before go-live.
We conduct:
- Unit tests: to verify the technical integrity of each migrated module or development
- Functional tests: to validate that all critical business workflows run as expected
- UAT (User Acceptance Testing): where key users test the new system and confirm it meets operational needs
- Performance testing: to ensure the system is stable, responsive, and ready to scale
We fix every issue before go-live and continuously gather feedback from your teams to improve usability and efficiency.
🎯 Goal: Ensure your new ERP is fully operational and secure before going live.
4. Go-live & hypercare – A controlled production launch
Once all tests are validated, we proceed with the final go-live. This step is carefully planned and executed to avoid any disruptions.
Our go-live process includes:
- Deploying during off-peak hours (evenings, weekends, or low-activity periods)
- Phased or full cut-over depending on your business and technical constraints
- Immediate post-go-live support from our experts to handle final adjustments
- Hypercare period: intensive support in the first few days to ensure a smooth transition
🎯 Goal: Deliver a smooth, stress-free go-live — with your business running at full speed from day one.
A proven methodology for a secure and optimized upgrade
Our 4-step approach ensures a well-prepared, high-value upgrade that supports your growth. In summary, our methodology relies on three pillars:
- Anticipation & structure: Detailed audit and planning from the start
- Optimization: Not just an update — a chance to streamline and enhance your ERP
- Support & guidance: From planning to go-live and beyond, we stay by your side
A migration strategy tailored to your business
Not sure which path is right for you? Here’s how we help you make the right decision.
Not every ERP migration should be handled the same way.
Every company has its own history, needs, and ERP complexity. Moving to a new Odoo version isn’t just a technical upgrade — it’s an opportunity to improve your system, optimize business processes, and reduce technical debt.
At Eezee, we offer two strategic migration approaches based on your current setup, business goals, and future roadmap:
Approach 1 : Clean & Rebuild
Who is it for?
- Businesses that have been using Odoo for several years and have accumulated technical debt or complexity
- Organizations with a large number of outdated or unnecessary customizations
- Teams that want to take this opportunity to rethink their workflows and align with best practices
What we do:
- Audit of current usage and rationalization of functional scope
- Elimination of obsolete customizations and database cleanup to reduce technical debt
- Rebuilding business workflows based on Odoo's latest features and best practices
- Retraining of users to support the adoption of the new system
Start fresh with an optimized system
Benefits :- A lighter, faster, and easier-to-maintain ERP
- A more standardized system, aligned with native Odoo upgrades
- Reduced long-term maintenance costs
- Future-proof architecture, easier to update going forward
Keep in mind:
- This approach introduces changes in user habits and may require additional change management
- It typically takes more time than a simple technical migration — but pays off in performance and sustainability
Approach 2 : Evaluate & Upgrade
Who is it for?
- Businesses with a well-structured ERP who want to upgrade without rebuilding everything
- Companies with strategic custom developments they want to retain
- Teams seeking a transition with minimal operational impact
What we do:
- Full mapping of all custom developments and installed modules
- Gradual code upgrade with integration of new Odoo features
- Rigorous testing in a staging environment before production
- Controlled data migration and carefully planned go-live
A smooth, controlled transition
Benefits :- Smooth transition that minimizes business disruption
- Critical custom features are preserved and adapted
- Faster go-live with less rework upfront
Keep in mind:
-
Technical debt isn’t fully eliminated — although it can be optimized
- Maintaining older customizations may limit adoption of some newer standard features
How to choose the right upgrade approach?
- Your ERP is heavily customized and slowing your operations?
→ Clean & Rebuild is the best fit. It allows you to remove technical debt, simplify your architecture, and realign your ERP with Odoo standards. - You want to migrate quickly while keeping your key features?
→ Choose Evaluate & Upgrade. It’s ideal for maintaining continuity while taking advantage of new features at your own pace. - Still unsure?
→ You can start with an Evaluate & Upgrade approach, then plan a post-migration optimization phase to streamline and standardize your system over time.
When should you upgrade?
The ideal upgrade timing depends on several factors: Odoo’s release cycle, your system’s current stability, industry changes, and your specific business needs.
Odoo releases a major new version every year, with improvements in performance, automation, UX, and security. But should you upgrade every time? Not necessarily.
Upgrading quickly may be a strategic move if:
- The new version introduces key innovations for your sector (e.g., logistics optimization, regulatory compliance, e-commerce updates, etc.)
- You work mostly with standard Odoo features, making the upgrade smoother and more affordable
- You’re on an outdated version: Odoo only supports the latest three versions — older ones may pose security or compatibility risks
Delaying the upgrade may make sense if:
- The new features don’t bring enough added value for your business right now
- You rely on many custom developments, making the upgrade more complex and costly
- Your company is undergoing major transformation — in this case, it’s wiser to stabilize your processes first
At Eezee, we recommend evaluating your ERP setup regularly to identify the best moment
to upgrade,balancing benefits, costs, and operational impact.
🎯 Our advice: upgrade every 3 years.
Book your demo now.How much does an Odoo upgrade cost?
The cost of upgrading to a new Odoo version depends on several factors: the complexity of your custom developments, the volume of data to be migrated, and most importantly, the migration approach you choose. The closer your ERP setup is to standard Odoo, the faster and more affordable the upgrade will be.
💡 Good news: upgrading standard Odoo is free!
That means if your ERP relies mostly on native modules without heavy customizations, moving to a newer version doesn’t involve any additional software cost.
However, if your system includes many custom developments, the number of lines of code to adapt will directly impact the budget. That’s why we follow a structured method to help you control costs and ensure a smooth migration:
- 1 day of technical and functional analysis per business area
- Full audit of your current system, with detailed documentation of workflows and technical configuration
- Personalized recommendations, including a comparison between your setup and Odoo’s latest standard features
- Planning and a detailed budget for a secure and optimized upgrade
Thanks to this approach, we help you transition smoothly and securely — while maximizing your ERP’s performance and keeping migration costs under control.
