Discover in this article how to anticipate the migration to avoid additional costs and guarantee the stability of your Odoo system.
I. Diagnostiquer son environnement Odoo avant toute migration
To anticipate the 25% increase, it is necessary to establish a complete diagnostics of your Odoo system.This latter should make it possible to identify not only the technical state, but above all the operational and financial impacts of a migration or maintenance on the current version.
1. Évaluer la version actuelle utilisée et son adéquation
The first step is to have your current Odoo system version assessed. This is done as follows:
Identify the version used and its age relative to the latest available versions.
Understanding the improvements introduced in the new versions: additional features, enhanced security, increased performance.
Evaluate whether your current version still allows you to achieve your business objectives without constraints.
2. Identifier les processus critiques et leurs usages
A highly customized critical process can make a migration complex and costly, whereas a standard feature could be quickly replaced or adapted. Therefore:
Identify the features actually used by the teams.
Identify the critical business processes (billing, procurement, production, financial reporting) that cannot be disrupted.
Measure the level of dependence on specific developments and external integrations.
3. Analyse des performances et risques opérationnels
Ces éléments permettront d’anticiper les coûts indirects d’une migration, comme l’impact sur les équipes et la productivité :
Check the stability of the current system: frequency of incidents, interruptions, or slowdowns.
Identify the sensitive points that could impact business continuity during the migration.
Determine if current processes still meet the company's growth and performance needs.
4. Audit fonctionnel et organisationnel
A a clear, structured and understandable report for leaders, presenting strengths, weaknesses and risks linked to each scenario: stay or migrate. It is crucial to make a:
Analysis of business processes: accounting, sales, purchasing, production, reporting.
Assessment of the alignment between current needs and available functionalities.
Identifying potential improvements or processes to simplify during migration.
Identification of critical dependencies between modules and processes.
5. Préparer une base de décision financière
Identification of critical dependencies between modules and processes.
Compare the cost of the license surcharge with that of a complete migration.
Identify potential long-term savings in the event of migration: simplified maintenance, increased productivity, reduced interruptions.
Assess the impact on the company's overall strategy: growth, digital transformation, compliance.
II. Planifier la migration : une démarche structurée
Planning is the strategic step that transforms the diagnosis into a concrete decision. A successful migration is not limited to the technical aspects: it involves coordination, resources, timing, and risk management.
1. Élaborer un plan clair et progressif
A successful migration relies on a rigorous planning.
The main steps include:
- The definition of a calendar realistic, taking into account the pace of the business;
- The preparing a test environment to simulate the migration before going into production;
- The module prioritization to migrate according to their strategic importance;
- L’involvement of the business teams from the very beginning of the plan's design.
In this sense, Baamtu is implementing a agile methodology for its partners : iterative planning, milestone tracking and continuous communication with the client.
2. Tester avant de migrer
Pre-migration tests allow you to:
- Verify the integrity of the transferred data;
- Ensure that the specific modules are functioning correctly;
- Identify the necessary adjustments before final deployment.
3. Simuler et tester la migration
For a smooth and secure transition, with minimal disruption to the business, the following will be necessary:
Replicating daily activities in a test environment.
Verify that all essential processes continue to function.
Detect and correct anomalies before production deployment.
4. Mesurer l’impact financier et stratégique
In order to make an informed, data-driven and justifiable decision, aligned with business and financial objectives, it is necessary to:
Compare the cost of the 25% surcharge with the cost of a complete migration.
Identify indirect benefits: increased productivity, simplified processes, better integration with other tools.
Evaluate the impact on the company's growth and digital strategy.
III. Accompagner le changement pour une adoption réussie
A successful migration is not limited to the technical aspects: it requires structured support so that teams fully adopt the new environment and the company derives a real strategic benefit from the update.
1. Former les équipes pour tirer parti des nouveautés
Each new version of Odoo brings improved features and new possibilities for automating and simplifying processes. To maximize the benefits, it is recommended to:
To expect training tailored to each employee's role so that they understand and use the new features.
Provide clear and concise materialsadapted to the daily reality of the teams.
Ensure a post-migration support to answer questions and adjust processes based on feedback.
2. Transformer la migration en levier stratégique
Migration is an opportunity to optimize the organization and improve overall performance.
Reliability and speed of processes Sensitive tasks such as invoicing, order tracking and accounting closings become smoother and more secure.
Visibility and monitoring of indicators : improved dashboards allow managers to obtain a clear, real-time view of company performance.
Security and Compliance : Migrating to a recent version reduces the risks associated with security vulnerabilities and ensures compliance with legal and regulatory obligations.
