Odoo upgrades
Move to Odoo 20 with your customisations understood, not broken
Odoo releases a new major version every year and supports each one for three years. If your database is falling behind, the risk grows quietly. We review every custom module, test the upgrade on a copy of your data, and move you across with no surprises.

Upgrade warning signs
Is your Odoo version holding you back?
Tap any that apply. Each sign points to a reason upgrades get postponed, and to the risk of postponing them again.
We are still on Odoo 16 or earlier
Root cause: Standard support for Odoo 16 ended in September 2025, so new bugs and security issues are no longer fixed under standard support.
Cost if ignored: You carry unpatched risk, or pay extra for extended support to stand still.
Custom modules are the reason we never upgrade
Root cause: Custom code must be updated to each new Odoo version by whoever maintains it, and often nobody owns that job.
Cost if ignored: The longer you wait, the more versions of change the code must absorb.
Odoo 17 felt new, but its support is ending
Root cause: Odoo plans standard support for Odoo 17 to end in September 2026, three years after its release.
Cost if ignored: A database that felt current becomes the next upgrade emergency within months.
Our integrations use XML-RPC or JSON-RPC
Root cause: Odoo has deprecated these older external APIs in favour of JSON-2, with removal of the remaining services already scheduled.
Cost if ignored: Integrations that work today can fail outright after a future upgrade.
We see new features but cannot use them
Root cause: Improvements arrive in new major versions, so an older database misses what Odoo has built since you went live.
Cost if ignored: Your team keeps workarounds that a newer standard feature already solves.
The last upgrade broke things we only found later
Root cause: The upgrade went straight to production without enough testing of real business flows on an upgraded copy.
Cost if ignored: Disruption after go-live, and a team that now fears every upgrade.

Each of these is manageable with the right preparation. We will show you what your upgrade really involves.
How we upgrade
Review, rehearse, then upgrade
We follow Odoo’s own upgrade process and wrap it in SCALE milestones. You see a tested, upgraded copy of your database before your live system changes, and you sign off each stage.
01Upgrade assessment
Know what you are dealing with.
What we do
We list every installed module, custom field, Studio change and integration, then classify each one: still needed, now covered by standard Odoo, or ready to retire. You get a clear view of effort before committing.
You receive
- Module and customisation inventory
- Classification of each customisation
- Upgrade plan and target version
“Which of these customisations would you build again if you started today?”
02Code and integration update
Bring custom work up to date.
What we do
Custom modules we keep are updated to the target version, and anything replaced by standard features is removed. Integrations still using the deprecated XML-RPC or JSON-RPC endpoints are moved to Odoo’s JSON-2 API.
You receive
- Custom modules updated to the target version
- Integration changes documented
“Which integration would stop trading if it failed on Monday morning?”
03Test upgrade
Upgrade a copy, not your live data.
What we do
We request an upgraded test database from Odoo and test it alongside your key users. Views, reports, email templates, automations and full business flows are checked against a test plan we agree with you.
You receive
- Upgraded test database
- Business flow test plan and results
- Fix log for every issue found
“Which month-end report must look exactly right before you will sign off?”
04Production upgrade
Switch over when use is lowest.
What we do
We schedule the production upgrade for a quiet window, because the database is unavailable while it runs. Afterwards we repeat the critical checks and stay on hand while your team settles into the new version.
You receive
- Agreed upgrade window
- Post-upgrade checks
- Short guide to what changed for users
“Who needs to know about the upgrade window, inside and outside the business?”

What is included
Our Odoo upgrade service covers
Upgrading is more than running a script. These are the pieces we take responsibility for, from first assessment to the week after go-live.
Customisation audit
Every custom module, Studio change and automation reviewed, with a recommendation to keep, replace with standard Odoo or retire it.
Custom module updates
Code we keep is updated to the target Odoo version, because Odoo requires custom modules to be ready before the database can be upgraded.
API modernisation
Integrations on the deprecated XML-RPC or JSON-RPC endpoints moved to Odoo's JSON-2 API, which uses API keys for authentication.
Test database and UAT
An upgraded copy of your database tested against your real business flows, with your key users involved before anything changes in production.
Production cut-over
The live upgrade scheduled for a low-usage window, followed by checks on critical flows, reports and integrations before your team returns.
User change briefing
A short, role-based summary of what looks and works differently in the new version, so users are not surprised on day one.
Hosting fit finder
Find your best-fit Odoo hosting model in 60 seconds.
Answer six quick questions. We will score each hosting model against your answers and explain why, just as we would in a consultation.
- Six questions, no email needed
- Explains the reasoning behind every result
- Based on Odoo’s official hosting rules
Our recommendation
This tool gives guidance only. Your final choice should follow a proper review of your requirements.
Honest fit
Is an Odoo upgrade right for you now?
This is right for you if
- You run Odoo 17 or earlier, on-premise or on Odoo.sh
- Custom modules or integrations have blocked past upgrades
- You want new standard features to replace old workarounds
- You can give key users time to test an upgraded copy
It is probably not right if
- You are on Odoo Online with only standard apps: Odoo's own upgrade route may be all you need
- Your processes no longer fit how you use Odoo at all: an optimisation review should come first
- You are moving to Odoo from another system: our Odoo migration service is the right starting point

We follow Odoo's process
Test database, business flow testing, then production. We use Odoo’s documented upgrade route rather than shortcuts that leave hidden problems behind.
Honest about custom code
We will tell you when a custom module is no longer worth keeping. Every module you retire is one less thing to upgrade next time.

FAQs
Questions buyers ask us
What is the latest version of Odoo?
Odoo 20 is the latest major version, released in autumn 2026. Odoo publishes a new major version roughly every year and provides standard support for each major version for three years, covering helpdesk support, bug fixing and security updates. We recommend planning upgrades well before your version leaves standard support.
What happens when our version leaves standard support?
Odoo stops providing standard bug fixes and security updates for it. Extended support is available for an additional fee, with bug fixes depending on feasibility. Odoo also only upgrades to supported versions, though the last unsupported version can still be an upgrade target for up to six months after its end of life.
Can we jump straight from Odoo 15 or 16 to Odoo 20?
Usually yes. Odoo’s upgrade process takes a database to a supported target version without stepping through every release in between. Your custom modules, however, must be updated to the target version, and the bigger the jump, the more change that code needs to absorb. Our assessment estimates that effort before you commit.
Does our Odoo Enterprise subscription cover the upgrade?
Odoo Enterprise includes upgrade requests for the standard database. Custom modules are only covered if they are maintained under Odoo’s paid arrangement for extra modules. Most businesses with custom code need a partner to update and test it, which is the work we take on.
Will the system be unavailable during the upgrade?
Yes, the production database is unavailable while the upgrade runs. That is why Odoo recommends planning it for a time when usage is minimal. Because we time the test upgrade first, you will know roughly how long the window needs to be before you book it.
Our integrations use XML-RPC. Will they still work?
Odoo has deprecated its XML-RPC and JSON-RPC endpoints in favour of the newer JSON-2 API. Some services are already removed in Odoo 20 and the rest are scheduled for removal in a later version. We check every integration during assessment and move those at risk to JSON-2.
