Common Difficulties in Database Migration and How to Solve Them
Migrating from one version of Odoo to another brings the promise of new features, performance improvements, and long-term support. But this journey isn’t without its share of roadblocks.
Below are the top challenges teams face during Odoo database migration, with practical solutions to each.
Custom Module Incompatibility
Refactor custom modules to match the latest Odoo API and architecture by reviewing official documentation and changelogs for deprecated elements. Test each module separately in a staging environment before full integration to ensure stability.
Data Structure Changes
Create a data mapping document to compare fields at the model level. Use OpenUpgrade for Community or request official scripts for Enterprise. During the dry run, validate each model to ensure relationships remain intact and no links are broken.
Third-Party Apps Not Supported in Latest Version
Contact the app vendor to confirm compatibility or obtain an updated version. If it's not available, consider replacing it with custom development or built-in features in the new version. Perform code reviews and update any deprecated functions manually as needed.
Downtime During Final Cutover
Run multiple test migrations to streamline the live cutover process. Apply delta migration methods to bring in new data added after the initial migration. Plan the final switch during off-peak hours or weekends to minimize disruption
Unclean or Incomplete Data
Clean up data before migration using Excel scripts or tools like OpenRefine to remove duplicates and ensure consistency. Involve business users to validate key data areas such as customers, products, and accounting records for accuracy
Failed Import Due to Format Issues
Ensure all CSV/Excel files are converted to UTF-8 format. Standardize date and number formats, and verify file encoding and separators before importing into Odoo to prevent data errors.
Security and Access Rights Conflicts
After migration, review ACLs and security rules to ensure proper access. Create a role mapping matrix to align old roles with the new setup, and test permissions with sample users before going live to confirm everything works as expected.
Complex Financial or Accounting Data
If full transactional migration is complex, use summarized opening balances instead. Rebuild reports in the new system and cross-check with exports from the old one. After migration, verify closing balances, tax reports, and reconciliations for accuracy.
Insufficient Testing
Perform functional, UAT, and load testing before go-live. Engage department heads to validate key processes such as sales, inventory, and accounting. Always have rollback options ready to handle any unexpected issues.
Lack of Documentation or Migration Plan
Create a detailed migration checklist and document all changes, including module updates, data mappings, and resolved issues. Assign clear ownership for each phase—technical, functional, UAT, and go-live—to ensure accountability and smooth execution.
