Odoo Migration, Upgrade & Downgrade Services
Move your Odoo instance to a newer version, jump from Community to Enterprise, or step back to a stable earlier release — with a reconciled database and refactored custom modules at every stop.
Version Upgrades
Moving v12, v13, v14, and v15 forward to v19.
Version Downgrades
Rolling back to a stable release when an upgrade misfires.
Community to Enterprise
Seamless transition onto Odoo Enterprise.
Custom Module Porting
Refactoring custom code for the new API and ORM.
Data Cleaning & Audit
Deduplicating and purging orphaned records first.
Upgrades and downgrades are different jobs
Going forward, we port your code to new APIs. Going back, we protect data written in a schema the older version doesn't know yet. We scope each one differently before quoting.
Moving to a newer version
For instances on v12–v17 that want current features, security patches, and long-term support.
- Deprecated API calls in custom modules get rewritten, not just patched.
- Removed or merged core modules are mapped to their v19 equivalents.
- New default view and workflow changes are reviewed with your team before cutover.
Rolling back to an earlier version
For instances stuck on a version that broke a critical workflow, or that upgraded before a required module was ready.
- Fields and tables introduced after your target version are identified and archived, not silently dropped.
- Records created under the newer schema are reconciled against the older data model field by field.
- We always run it on a staging copy first — a downgrade is not something to test in production.
Five steps, one weekend
Everything after the audit happens on a copy of your database. Your live instance stays untouched until the final cutover window.
Audit
We inventory your custom modules, third-party apps, and current version's known deprecations.
Staging run
A full copy of your database is migrated first, on infrastructure that mirrors production.
Reconcile
Automated scripts compare financial balances and stock valuation before and after, line by line.
Sign-off
Your team reviews the staging instance and approves the exact cutover window with us.
Cutover
The live migration runs in an off-peak window, with the previous database kept as a fallback.
The Synodica Odoo Migration Advantage
We run full staging dry runs and automated database reconciliation scripts to verify financial balances and stock valuation before performing the live cutover.
- 100% Reconciliation Audit: Every dry run produces a reconciliation report you can read before we go live.
- Zero-Risk Database Rollback: The previous database is retained and restorable for a defined rollback window.
- Off-Peak Live Cutover: Cutover windows are scheduled off-peak, with a fixed go/no-go checkpoint.
- Upgraded Data Integrity: All historical sales, accounting, and inventory balances are matched and verified.
Questions Before a Migration
Anything specific to your setup gets covered in the migration audit.
How long does an Odoo version upgrade or downgrade take?
Typically 1–3 weeks for staging preparation, data cleaning, and custom code refactoring, followed by a live cutover during an off-peak weekend window (usually 4–12 hours of downtime).
Can custom modules be ported to Odoo 19?
Yes. We review your custom Python models, views, and JavaScript web client assets, refactoring obsolete ORM methods and API calls to ensure full compatibility with Odoo 19.
What happens to existing transaction data during migration?
All historical records—including accounting journal entries, stock moves, sales orders, and customer history—are fully preserved and reconciled using automated audit scripts.
Is it possible to migrate from Odoo Community to Odoo Enterprise?
Absolutely. We handle seamless Community-to-Enterprise transitions, enabling native Enterprise apps (Accounting, Studio, Documents, Barcode, etc.) while preserving all existing Community data.
How does a version downgrade work if an upgrade was unsuccessful?
If an upgrade was attempted prematurely, we analyze schema changes, archive data structures created in newer versions, and safely map your database back to a stable release without data loss.
