Odoo Version Upgrade Services
Odoo upgrade services from Reldanor move your database to a newer Odoo version — for example from Odoo 16, 17 or 18 to Odoo 20 — without losing data or breaking the way your team works. Reldanor runs the upgrade on a staging copy, ports your custom modules, validates the data and plans a short go-live window.
A well-planned Odoo version migration gives you new features, better performance and continued support from Odoo S.A.
When should you upgrade Odoo?
Odoo releases a new major version every year and supports recent versions for a limited time. An upgrade is worth planning when:
- Your version is approaching or past the end of Odoo's support period
- You need features or apps only available in newer versions
- Custom modules are blocking upgrades and the gap keeps growing
- Performance or usability problems are fixed in newer versions
- You are moving from Odoo Community to Odoo Enterprise

Our process
Assessment
Reldanor inventories modules, customizations and integrations. Your preparation: give access to the database and any custom code.
Test upgrade on staging
A copy of production is upgraded and checked for errors.
Porting and fixes
Custom modules are ported and issues are fixed on staging.
Validation and user testing
Data is validated and key users test their workflows. Your preparation: assign testers and reserve time.
Go-live
The live database is upgraded in an agreed window and monitored after the switch.
How we scope your project
Upgrade effort depends mainly on the number of versions you skip, how much custom code needs porting, third-party modules, integrations and the size of the database.
A database using only standard apps usually upgrades with little effort; heavily customized databases need more porting and testing.
Every project is scoped individually — contact us for a free consultation.
Limitations and when you need something else
Some things to know before upgrading:
Frequently asked questions
How long does an Odoo upgrade take?
A standard database can be upgraded and tested in a few weeks. Databases with many custom modules or several versions to skip take longer. Reldanor gives a timeline after the assessment.
Can we skip versions, for example upgrade Odoo 16 to Odoo 20?
Yes. Odoo's upgrade service can move a database across several versions. Custom modules still need porting to the target version.
Will we lose data during an Odoo upgrade?
No, when the upgrade is tested first. Reldanor validates key figures on staging before the production upgrade.
What happens to our custom modules?
Each custom module is reviewed. Some are replaced by new standard features; the rest are ported to the new version and tested.
Can you upgrade from Odoo Community to Odoo Enterprise?
Yes. Reldanor migrates Community databases to Enterprise and enables the additional apps you need.
