Odoo Migration:change versions without losing your data.
Evolve the version or environment without breaking essential uses.
Prepare an Odoo migration →
Migrating Odoo is not just about changing versions. It is a project that involves stability, modules, data, specific developments, and business continuity.
SIGNS THAT A MIGRATION IS NECESSARY
Version that is aging - incompatible modules, degraded security |
Declining performance - unexplained slowdowns, frequent instability |
Blocked features - your version does not include what you need |
Increasing technical risk - deferring increases debt and future cost |
WHY MIGRATE
Security, maintainability, compatibilityand functional evolution.
A migration becomes necessary when the current version ages, when certain modules are no longer sustainable, when performance degrades, or when the company wants to benefit from improvements available in a newer version.
Delaying the migration for too long often increases the overall risk. The greater the gap between the old and new version, the more complex the recovery.
To be successful, a migration must be thought of asa controlled transition, not as a purely technical operation carried out overnight.

HOW IT WORKS
A trajectoryorganized upstream.
A well-managed migration follows three distinct phases. Each phase has its own
tasks, its own leaders, and its own validation points.
PHASE 1
Before the migration
✓Audit of the existing environment
✓Inventory of modules and dependencies
✓Identification of sensitive areas
✓Sorting of specifics: keep, rewrite, abandon
✓Definition of strategy and target scope
✓Preparation and cleaning of data
PHASE 2
During the migration
✓Setting up the target environment
✓Data migration in test environment
✓Adaptation of specific modules
✓Testing critical flows with teams
✓Correction of detected anomalies
✓Final validation before switch
PHASE 3
After the migration
✓Switch to production accompanied
✓Intensive monitoring in the first days
✓Correction of residual friction points
✓Training reminder if necessary
✓Stabilization and post-migration assessment
✓Documentation of the final environment
THE KEY SUBJECT
What has been developed or customizedmust be reevaluated.
A migration is often the right time to sort: what remains useful, what can return to standard, what needs to be rewritten, and what unnecessarily complicates the ERP.
The quality of data recovery is equally crucial. A new environment does not automatically correct a poorly prepared history — data issues remain intact in the new version if not addressed beforehand.
Keep | The development remains relevant and still meets a real need. It will be migrated and adapted to the new version. |
Rewrite | The need still exists but the code is outdated or could be done better. Start fresh rather than carry debt. |
Standard | The new version of Odoo natively covers what was specific. We remove the development and revert to the standard. |
Abandon | The need no longer exists or was not useful enough. We lighten the ERP and avoid carrying unnecessary code. |
DECISIONS TO BE MADE ON EACH SPECIFIC
A migration is an opportunity to simplify. Teams that approach it this way arrive on the new version witha cleaner Odoo than the one they left..
Migration from another tool
Are you migrating from WinBooks, Sage BOB, or Excel?
This is not a version update, but a complete change of environment. These migrations require a specific data recovery phase: extraction and cleaning of source data, mapping to the Odoo structure, import into a test environment, and business validation before switching.
Wappli regularly supports Belgian SMEs in this type of transition. The key is not to attempt to import raw history without preparing it - past inconsistencies do not disappear on their own in the new tool.
WinBooks
Accounting export, chart of accounts, journals, customers, and suppliers. Cleaning and mapping to Odoo accounting.
Sage BOB 50 / 500
Extraction of management data, recovery of items, contacts, and movements. Validation before import into production.
Excel & in-house tools
Data structuring, duplicate detection, format normalization. Clean import into Odoo via native tools.
A good integrator must know how to challenge the need, set a clear framework, explain the consequences of choices, and avoid unnecessary developments.
CHOICE CRITERIA
Business understanding, arbitration capacity, andimplementation quality.
WAPPLI SOLUTION
Systematic audit of source data before any import. Cleaning, deduplication, and validation in a test environment.
WAPPLI SOLUTION
Systematic audit of source data before any import. Cleaning, deduplication, and validation in a test environment.
RISK
Unprepared data
Importing raw data without prior audit generates inconsistencies that are difficult to correct after the switch.

WAPPLI SOLUTION

WAPPLI SOLUTION
Systematic review of each specific: keep, rewrite, revert to standard, or abandon. Documented decision.
RISK
Specifics not reassessed
Carrying all past developments without sorting unnecessarily burdens the new version and creates technical debt from the start.
RISK
Unprepared data
Importing raw data without prior audit generates inconsistencies that are difficult to correct after the switch.
Secure and maintained environment
Recent version, compatible modules, access to Odoo security patches.
Reliable and consistent data
The retrieved history is clean, deduplicated, and aligned with the Odoo structure. No problematic inheritance.
Simplified architecture
Unnecessary specifics have been discarded. The remaining code is clean and documented.
PRODUCT MIGRATION
Finding a healthier base toevolve the ERP.
Beyond the version change, a successful migration is often an opportunity to simplify some past choices, stabilize the environment, and start over with a more maintainable architecture.
Users need to regain their essential reference points. A well-managed migration anticipates the effects on teams, secures essential uses, and avoids unnecessary disruptions at the time of the switch.
This is what allows for using Odoo with more confidence and less fragility.
Operational teams from the switch
Prepared, trained, and supported. Critical flows operate from day one.
Healthy foundation for the following developments
New modules, new features, PEPPOL: everything becomes accessible on a maintained version.
Let's talk about your Odoo migration
We assess your current version, your modules, the state of your
data, and we tell you what a migration actually entails.
