Successful Migration to Dolibarr: Complete Guide

All the tips and best practices for migrating your data from another ERP to Dolibarr without business interruption.

Why migrate to Dolibarr?

The decision to migrate to a new ERP is never trivial. However, Dolibarr offers compelling arguments that justify this transition. As an open-source solution, Dolibarr eliminates recurring license costs that weigh on SME budgets. Its modular architecture allows you to activate only the features you actually need, avoiding the unnecessary complexity of monolithic solutions. The active community surrounding the project ensures regular updates and a very rich ecosystem of complementary modules.

Modular architecture adaptable to each company's specific needs
Active community with thousands of complementary modules
Intuitive interface that reduces training costs
Interoperability with existing tools via REST API

Phase 1: Audit and planning

Every successful migration starts with a thorough audit of your existing system. This phase is crucial and should not be neglected. Start by inventorying all data present in your current ERP: clients, suppliers, products, invoices, order history, etc. Then identify the critical business processes your team uses daily. This mapping will allow you to define the exact scope of the migration and anticipate any potential blocking points.

Phase 2: Data mapping

Data mapping is the most délicate technical step of the migration. It involves matching fields from your old system with those in Dolibarr. Some data maps naturally (client name, address, phone number), but others require transformations or regrouping. Custom fields from your old ERP will need to be recreated in Dolibarr as extra attributes. Document each correspondence in a mapping table to ensure traceability.

Create a correspondence table for each entity (clients, products, invoices)
Identify fields requiring format transformation
Define strategy for custom fields and extra attributes
Handle cases of missing or incomplete data
Plan cleanup of obsolete data before migration

Phase 3: Technical migration

Technical migration can be carried out in several ways depending on data volume and configuration complexity. For small structures, module-by-module CSV import is often the simplest and most controlled solution. For larger volumes, using Dolibarr's REST API allows automating data transfer via scripts. In the most complex cases, direct database migration can be considered, but it requires excellent knowledge of Dolibarr's schéma.

CSV import: ideal for small volumes and simple migrations
REST API: recommended for medium volumes with automation
Direct SQL migration: reserved for experts with very large volumes
Third-party ETL migration tools for complex transformations
Custom Python or PHP scripts for specific cases

Phase 4: Testing and validation

The testing phase is absolutely critical. Never skip this step, even if deadlines are tight. Start by verifying the integrity of migrated data: count records, verify financial totals, check client balances. Then have key users in your organization test the main business processes. Ask them to perform their daily tasks in the test environment and report any issues or discrepancies found.

Data integrity verification: counts and control totals
Functional testing of critical business processes
Validation by key users in each department
Performance testing with actual data volume
Verification of access rights and permissions
Testing document generation (invoices, quotes, purchase orders)

Phase 5: Go-live and support

The big day has arrived. To minimize risks, we recommend a planned switchover strategy, ideally over a weekend or low-activity period. Plan a final data synchronization from the old system to capture recent transactions. Keep the old ERP accessible in read-only mode during a transition period of a few weeks. Train your teams before the switchover and plan enhanced support during the first days.

Keep the old system in read-only mode as référence
Ensure enhanced support during the first 2 weeks
Document new procédures for users
Plan a post-migration review after 1 month of use

Special cases: migration from Sage or Odoo

If you are migrating from Sage, know that export formats are generally well documented and most accounting data can be exported in CSV format or via FEC files. For migration from Odoo, Odoo's XML-RPC API allows extracting data programmatically, greatly facilitating the process. In both cases, invoicing and accounting data typically constitute the most délicate part of the migration. Engage a Dolicraft integrator to secure this step.

Sage: FEC export for accounting, CSV for commercial data
Odoo: extraction via XML-RPC API or native CSV export
