Stuck on an Old Version. Or Stuck With a Bad Implementation. We Fix Both.
Clean Odoo migrations from v11 to v18 — data intact, customisations rebuilt properly, nothing lost. And if your current Odoo is a mess someone else left behind — we rescue it, stabilise it, and make it work the way it should have from day one.
You're either stuck on an old version — or stuck with someone else's mess. Both are fixable.
Businesses come to us from two very different situations. Both are more common than most people admit.
The Version Problem
You're running Odoo v11, v12, v14, or v15. Your system works — mostly. But every month the gap between your version and the current one grows wider. Features you need aren't available. Security patches aren't coming. Your customisations are increasingly fragile. And the longer you wait, the bigger and more expensive the migration becomes.
The reason most businesses stay on old versions isn't that migration is impossible. It's that they've been told it's risky, expensive, and disruptive — usually by a vendor who either can't do it properly or wants to charge a premium for the anxiety. A well-planned Odoo migration is none of those things.
The Rescue Problem
Your Odoo was implemented by someone who over-promised and under-delivered. The system is live but barely functional. Customisations are undocumented, fragile, and break on every update. Your team has given up on certain modules. You've inherited code nobody wants to touch. The original vendor is unreachable or unresponsive.
This is more common than the Odoo ecosystem admits. Businesses come to us every month having spent significant money on an implementation that left them worse off than before. The damage isn't permanent — but it requires someone willing to go to the root of what's broken and fix it properly. That's exactly what Rootlevel does.
The common thread between both situations:
Whether you are moving away from an legacy version or escaping a failed implementation project, the underlying risks to your day-to-day operations are exactly the same.
The Rootlevel Standard
Rootlevel migrations and rescues are planned, tested, documented, and built to last.
Data integrity at risk
Migrations done carelessly lose records, corrupt relationships, and create accounting discrepancies that take months to untangle. Rescues done superficially paper over data problems that compound over time.
Customisations rebuilt badly
Most migration failures happen because custom modules are carried over without being rebuilt for the new version. They work — until they don't. Usually at the worst possible moment.
No testing before go-live
A migration without proper UAT is a gamble. A rescue without systematic testing is a patch. Both eventually fail.
No documentation left behind
After the migration or rescue, the vendor leaves. No documentation. No handover. You're dependent on them forever — or you're starting from scratch again.
Everything from audit to go-live — with nothing left undocumented.
Full Audit of Existing Installation
Before we migrate or rescue anything, we understand everything. A complete audit of your current Odoo installation — version, modules active, customisations present, data quality, server configuration, third-party integrations, and known issues. The audit produces a clear picture of what exists, what works, what's broken, and what needs to be rebuilt. No surprises mid-project.
Migration Planning & Risk Assessment
Every migration carries risk — the job is to identify it before it becomes a problem. We map every customisation against the target version, identify breaking changes, flag data transformation requirements, and produce a migration plan with clear milestones, rollback procedures, and go-live criteria. You know exactly what the migration involves before it starts.
Data Migration with Integrity Validation
Your data — customers, suppliers, products, inventory, accounting records, historical transactions — migrated to the new version with full integrity validation at every stage. We don't move data and hope for the best. Every record is validated against the source before go-live is approved. Opening balances verified. Historical data accessible. Nothing lost.
Custom Module Rebuild for New Version
This is where most migrations fail — and where Rootlevel's standard is highest. Every custom module rebuilt for the target version using current Odoo development standards. Not carried over. Not patched. Rebuilt properly — with full documentation, test coverage, and migration-proof architecture so the next version upgrade doesn't create the same crisis.
Third-Party Integration Re-establishment
Every integration your current Odoo has — payment gateways, eCommerce platforms, shipping APIs, WhatsApp, Google Workspace — tested, reconfigured, and validated in the new version before go-live. Integrations are the most commonly broken element in a migration. We treat them as first-class deliverables, not afterthoughts.
Server Optimisation Post-Migration
A new Odoo version on an old server configuration is a performance problem waiting to happen. Post-migration server review — PostgreSQL optimisation, memory configuration, Nginx setup, SSL, backup procedures, and security hardening. Your new Odoo runs on infrastructure configured for it, not infrastructure inherited from three years ago.
UAT & Parallel Running Period
Full User Acceptance Testing with your team before go-live. For high-risk migrations, a parallel running period where both old and new systems run simultaneously — so your team can validate the new system against the old without operational risk. Go-live only happens when your team has signed off on every critical workflow.
Post-Migration Support & Monitoring
Close monitoring in the first two to four weeks post go-live. Issues caught and resolved before they impact operations. Performance benchmarked against pre-migration baseline. Retainer options available for ongoing support, further customisation, and the next version upgrade cycle — so you're never in this situation again.
Planned. Staged. Tested. Documented.
Audit & Risk Mapping
Complete audit of your existing installation. Every module, every customisation, every integration, every known issue. Risk mapped against the target version or the rescue requirements. Output: a clear audit report and a proposed engagement plan with timeline and cost.
Migration or Rescue Plan
Detailed project plan with every deliverable named, every milestone dated, and every risk mitigated. For migrations: version upgrade path confirmed, breaking changes identified, data transformation mapped. For rescues: priority fixes identified, critical workflows stabilised first, full rebuild plan scoped.
Staged Execution
Migration or rescue executed in stages — never all at once. Staging environment used for all development and testing. Your production system untouched until every stage is validated. Weekly progress updates so you always know where the project stands.
UAT & Validation
Full User Acceptance Testing with your team. For migrations — every workflow tested against the old system. For rescues — every previously broken workflow tested against the fixed version. Go-live criteria defined upfront and verified before any production cutover.
Go-Live & Post-Live Support
Production cutover with us on call. Close monitoring for two to four weeks post go-live. Issues resolved immediately. Performance validated. Documentation handed over. Retainer options available for ongoing support and the next upgrade cycle.
If your Odoo is holding your business back — it's time to fix it.
This is right for you if:
- You're on Odoo v11, v12, v14, or v15 and need to upgrade to a supported version
- Your current customisations break on every Odoo update
- You inherited a broken or undocumented Odoo implementation from a previous vendor
- Your data has conflicts, duplicates, or integrity issues that nobody has fixed
- Your integrations stopped working after a version update
- You want your next Odoo version upgrade to be a planned, managed process — not a crisis
- You need a vendor who will document everything so you're never dependent on them again
This is probably not right for you if:
- You want a migration done in 48 hours with no audit — that's how data gets lost
- You're on a heavily customised Community installation and expect zero rebuild cost
- You want the cheapest quote regardless of data integrity guarantees

Every version we've worked with. Every upgrade path we've executed. We migrate both Community and Enterprise across Odoo SH, self-hosted, and cloud deployments.
| From | To | Complexity | Difficulty | Our Experience |
|---|---|---|---|---|
| v11 | v17 | Multi-hop migration | High | Live client — India EMS manufacturer |
| v15 | v17 | Two version jump | Medium | Multiple projects |
| v16 | v17 | Single version | Low-Medium | Multiple projects |
| v17 | v18 | Single version | Low-Medium | Live clients — Belgium & Germany |
| v17 → v18 | v19 | Sequential migration | Medium | Live client — Belgium EV retailer |

Data & Migration Tools
Migration and rescue are different problems. Here's how we approach each.
| Comparison Factor | Odoo Migration | Odoo Rescue |
|---|---|---|
| Starting point | Working system on old version | Broken or abandoned system on any version |
| Primary goal | Move to new version cleanly | Stabilise, fix, and rebuild properly |
| Data work | Migration with integrity validation | Data audit, conflict resolution, deduplication |
| Custom module work | Rebuild for new version | Audit, document, rebuild or replace |
| Timeline | 3–8 weeks depending on complexity | 4–12 weeks depending on damage |
| Risk profile | Manageable with proper planning | Higher — unknown variables until audit |
| Outcome | Clean, documented, version-current Odoo | Stable, documented, properly configured Odoo |
Both end in the same place — a system your team can rely on, with documentation that means you're never dependent on any single vendor.
Three version migrations. Two countries. One standard — migration-proof.
We don't just talk about Odoo rescue and upgrades. We deliver them in complex production environments across different continents.
Odoo v17 → v18 → v19 — Sequential migration
Retail & EV Mobility — Belgium
A Belgian EV retailer needed their heavily customised Odoo Studio installation to survive not one but three consecutive version migrations. Every custom field, every automated workflow, every QWeb report — rebuilt to Odoo's official development standards.
95% migration-proof codebase across V17 → V18 → V19. The 5% affected was limited to Odoo backend changes outside any vendor's control.
Odoo v17 → v18 — Full migration in under one week
Managed IT Services — Germany
A German MSP running a Docker-based Odoo 17 Enterprise installation with CI/CD needed a clean V18 migration without disrupting their live client operations. Custom modules, AI integrations, multi-company setup, and helpdesk configurations — all migrated and validated.
Complete V17 → V18 migration delivered in under one week. Zero downtime. All customisations intact.
Odoo v11 — Rescue & Stabilisation
Electronics Manufacturing — India
An Indian EMS manufacturer inherited a broken Odoo v11 installation with GST compliance built by an unaccountable freelancer, an unmanaged server, data conflicts across multiple companies, and 200+ unresolved issues. 70+ users depending on a system that wasn't working properly.
GST compliance rebuilt from scratch. Server hardened and optimised. Data conflicts resolved. 200+ issues fixed. 70+ users operating cleanly on a stable, documented system.
