SECTION 01

What is Odoo Migration?

Odoo migration means moving your Odoo system from an older version to a newer version. This can include customer data, product data, invoices, sales orders, purchase orders, inventory, employees, accounting data, custom modules, Odoo settings, and third-party integrations.

Odoo migration is different from installing Odoo from scratch. With a new Odoo installation, you start with a new database. With an Odoo migration, you keep your existing business data and move it to the new version. The goal is simple: when your team starts using the new Odoo version, they should still have access to the business data and processes they were using before.

Odoo Update vs Odoo Migration

These terms can be confusing. A small update happens within the same Odoo version. For example: Odoo 19.0.1 → Odoo 19.0.2. An Odoo migration is a move from one major version to another. For example: Odoo 18 → Odoo 19 or Odoo 19 → Odoo 20. Major Odoo upgrades can require changes to the database, custom modules, and integrations.

Odoo releases a new major version roughly every year. Each new version can change the database, the way apps work, and the tools used to build custom modules. That is why custom modules and settings from an older version need to be checked and updated for the new version.

SECTION 02

Why Should Businesses Upgrade Odoo?

Staying on an old Odoo version may seem easier because your team already knows the system. But older versions can create problems over time. Here are some common reasons businesses upgrade Odoo.

security

Security Updates

Older Odoo versions eventually stop receiving security updates. Using an unsupported version can increase security risks for your business data.

new_releases

New Odoo Features

New Odoo versions add new features and improve existing ones. These can include improvements to accounting, manufacturing, reporting, website, inventory, sales, user interface, and automation.

extension_off

Support for Odoo Apps

Third-party Odoo apps and modules may stop supporting older Odoo versions. Upgrading helps you continue using newer apps and features.

groups

Finding Odoo Developers

Most Odoo developers work with newer versions. Finding developers for very old Odoo versions can become harder and more expensive.

integration_instructions

Third-Party Integrations

Payment systems, shipping services, marketplaces, and other software also change over time. An old Odoo version may eventually have problems working with newer systems.

It is better to plan your migration before you have a serious problem. Starting early gives your team enough time to check the system, fix problems, test everything, and plan the final upgrade.

SECTION 03

Odoo Version History

Each major Odoo version brings new features and changes.

Odoo 16 End of Life

Released in 2022. Odoo 16 improved the user interface and added improvements to areas such as manufacturing, shop floor, email marketing, and website. Odoo 16 is now an older version and businesses using it should plan their upgrade.

Odoo 17 End of Life

Released in 2023. Odoo 17 added improvements to several Odoo apps, including accounting, field service, subscriptions, IoT, and studio. Businesses with custom Odoo modules may need to update their custom code when moving from Odoo 17 to a newer version.

Odoo 18 Maintenance

Released in 2024. Odoo 18 added new features and improvements across many areas of the platform, including manufacturing, accounting, communication, database performance, and AI-assisted features.

Odoo 19 Supported

Released in 2025. Odoo 19 introduced AI agents throughout the platform, over 50 industry-specific packages, ESG reporting, and an enhanced user interface with compact Kanban views.

Odoo 20 LTS — Current

Released in 2026. Odoo 20 adds plain language AI agents that build automations, create records, and run on schedules. It also includes updates to bank reconciliation, offline mode, and introduces an MCP connector. Businesses planning a major Odoo upgrade can consider Odoo 20 as a migration target.

info
Can You Move Directly From Odoo 16 to Odoo 20?

Yes, an Odoo migration can move across multiple major versions. For example: Odoo 16 → Odoo 20. However, the migration still needs to deal with the changes made between each Odoo version. Your database and custom modules need to be checked and updated for the new version.

SECTION 04

Odoo Migration Process: Step by Step

A good Odoo migration should be planned and tested before the new version goes live. Here is the basic process.

01

Check Your Current Odoo System

First, we check your current Odoo version, database, installed Odoo apps, custom modules, business data, third-party integrations, and amount of data. This helps us understand what needs to be changed.

02

Check Custom Modules

Custom Odoo modules need special attention during migration. We check each module to see what needs to be changed, what can stay the same, what needs to be rewritten, and whether the new Odoo version already has the same feature.

03

Move and Update the Data

The database needs to be changed so it works with the new Odoo version. This may include changing old fields, data formats, and other database information. The data is also checked after the migration.

04

Test Everything

The migrated Odoo system is placed on a test server. Your team can then check real business data and processes before the new version goes live. We test sales, purchases, accounting, inventory, manufacturing, reports, custom modules, and integrations.

05

Move to the New Odoo Version

Once testing is complete, the final migration is done. This is normally planned during a time when the business is less busy, such as a weekend. A backup and rollback plan should also be ready before the migration starts.

06

Support After Migration

After the new Odoo version goes live, some small issues may appear when employees start using the system. The migration team should monitor the system and fix these issues during the first few weeks.

SECTION 05

What Happens to Custom Odoo Modules?

Custom Odoo modules are often one of the biggest parts of an Odoo migration. Custom modules are features that were built specifically for your business because the standard Odoo apps did not provide what you needed.

When you move to a new Odoo version, these modules need to be checked. Some may only need small changes. Others may need to be rewritten. Sometimes, the new Odoo version already includes a feature that replaces an old custom module.

Odoo changes from one version to another. These changes can affect Python code, database structure, screens and views, Odoo APIs, JavaScript, and security rules. Because of this, custom modules built for an older version may not work correctly on the new version.

tips_and_updates
Odoo Migration Is Also a Good Time to Clean Up Custom Code

Migration gives businesses a chance to review old custom modules. We can remove unnecessary code, replace old workarounds, and improve modules that have become difficult to maintain. This can make the new Odoo system easier to manage and upgrade in the future.

SECTION 06

Common Odoo Migration Problems

Odoo migration can become difficult when important steps are skipped. Here are some common problems.

01

Not Checking All Odoo Modules

If you do not check every installed module before migration, problems can appear later.

check Create a complete list of standard and custom modules and check each one before starting.
02

Not Testing Enough

A migration may look successful but still have problems with data, reports, or business processes.

check Test the new Odoo version with real business data before going live.
03

No Backup or Rollback Plan

If something goes wrong during the final migration, you need a way to return to the old system.

check Have a clear backup and rollback plan before starting the production migration.
04

Moving Bad Data to the New System

Old databases can contain duplicate, outdated, or incorrect data. Moving this data to the new Odoo version does not fix the problem.

check Review and clean important data before migration.
SECTION 07

How Long Does Odoo Migration Take?

There is no single timeline for every Odoo migration. The time depends on your Odoo version, database size, custom modules, integrations, and how much testing is needed.

Small Odoo System Standard Odoo with little customization and less than 50,000 records
4 – 6 weeks
Medium Odoo System Some custom modules, a few integrations, and 50,000–500,000 records
6 – 12 weeks
Large or Complex Odoo System Many custom modules, several integrations, and a large amount of data
3 – 6 months

The biggest factors are the number of custom modules, complexity of custom code, amount of business data, number of integrations, data quality, and time available for testing.
