Move to Odoo 19. Bring everything with you.
Version upgrades, SaaS-to-on-premise moves, and full data migrations — handled without data loss, downtime surprises, or half-working custom modules on the other side.
What an Odoo migration actually covers
A migration isn't just hitting "upgrade." Here's every layer we handle.
Version Upgrade
Upgrade your Odoo instance from v16, v17, or v18 to Odoo 19 — including all standard module configurations and system settings.
Data Migration
Full migration of your production database: customers, vendors, products, inventory, accounting history, CRM records, and attachments.
Custom Module Porting
Every custom module is reviewed, rewritten where needed, and made compatible with Odoo 19 APIs. We don't just hope it works.
Third-Party Integration Retesting
All external integrations — Shopify, Stripe, shipping APIs, payment gateways — are retested against the new instance before go-live.
User Acceptance Testing
We run structured UAT with your team against real migrated data. Sign-off happens before we flip the switch.
Five phases. No surprises.
Assessment
Week 1We audit your existing instance: custom modules, data volume, integrations, and known pain points. You get a written migration plan with fixed timeline and price.
Staging Migration
Weeks 2–3We migrate a full copy of your production database to a staging environment on Odoo 19. No impact to live operations.
Module Compatibility Audit
Weeks 3–4Every custom module is tested on staging. Incompatible code is rewritten. Integration connections are reconfigured and retested.
Full Data Transfer
Week 5Final production data is migrated with delta sync to capture changes since the staging run. Data integrity checks run automatically.
UAT & Go-Live
Weeks 5–6Your team runs UAT on the staging environment. Issues are fixed. Go-live is coordinated for minimal disruption — typically a weekend cutover.
Which migration path applies to you?
Odoo v16 → v19
Three major versionsLargest delta. Custom modules typically need a full rewrite. We've done this path 15+ times.
Odoo v17 → v19
Two major versionsMore straightforward. Most standard modules port cleanly. Custom work varies.
Odoo v18 → v19
One major versionUsually the smoothest migration. Most custom modules need minor API adjustments.
SaaS → On-Premise
Platform changeMove off Odoo.sh or odoo.com cloud onto your own server or VPS. Gives you full control over custom modules and data.
On-Premise → Cloud
Platform changeLift your self-hosted instance to a managed cloud environment. Better reliability, easier upgrades going forward.
Merging Two Instances
Data consolidationTwo companies, two Odoo databases. We merge them into one multi-company instance without losing historical records.
Five honest reasons — and what we do instead
- No pre-migration audit. We spend a full week assessing before writing a single migration script.
- Custom modules left untested. Every module gets a compatibility report before we start the migration run.
- Data cleaned only after migration. We clean and normalise data on the source first — duplicates, orphaned records, broken foreign keys.
- No rollback plan. We keep your old system live until UAT sign-off. 48-hour rollback window remains open post go-live.
- Users not trained on the new version. Every migration includes a training session on Odoo 19 UI changes and new features.
