How to Seamlessly Migrate Odoo from Older to a Newer Version?

The Odoo company periodically releases a new version of the system with some advantages over the old ones. There are currently Odoo 9 and 10 versions on the market, and the latest one is the 15th version, released in October 2021.
Migrating to a more recent version of Odoo is long and demanding. It can often be associated with many unexpected complexities and take time. Therefore, it is important to foresee possible difficulties and migrate quickly. In the following article, we’ll cover all the challenges of Odoo migration from one version to another. How does it work? What should you know about such a transition? Let’s get to know all the tiny details!

How Does It Work?

When you decide to migrate your older version of Odoo to a newer one, it is critical to determine the right strategy for the migration by answering the following questions:

  • What is the server hosting solution you are using?
  • What is the edition of your system? Enterprise or Community?
  • What is the original & target version of your system?

Make Analysis

Odoo enhances its abilities from version to version. New features are coming, and it is essential to understand how these changes influence the system and its functionality. When you use an older version in which some functions are not available, you customize it in your system. Make sure the whole system is ready to be updated to a new version.

Update the Customization

When you have defined which custom modules need to be upgraded for the new version of Odoo, it is time to update the module code. Some modules can work almost out of the box (only slight changes to the manifest file). The others might require more complex changes.


When the customization is done, the company should be ready to upgrade its database. The upgrade process can differ depending on the currently used hosting solution. After the migration process and the upgrade, developers can re-import or adapt data to work for the new Odoo version or configure modules.

The Price of Odoo Migration

Price and migration time depend on the Odoo version your company uses, installed modules, and other factors (server credentials, inline corrections, and other cases). To migrate from Odoo Community to Odoo Community, you’ll be charged for the base, custom modules, and data migration. Time depends on the level of customization.

The Migration process works as follows: 

  • Company uploads the database.

A developer creates a backup of the database and uploads it. There’s a possibility to anonymize all the data before uploading the database. 

  • Company migrates and tests the database.

Once the developer receives the database, they run the migration process and test it.

  • Company customizes the migration process to the database.

The migration process is mainly automated, yet some manual work may also be required, depending on the data’s sophistication. Because of the Odoo migration process complexity, the company can face some difficulties during that process; then, the developer needs to customize the scripts for the database. 

Such an operation may last at least from 2 to 4 weeks. After the script adaptation, the company receives an email with a link where they can download a migrated database.

Odoo Enterprise Migration

Odoo provides a genuinely comfortable and user-friendly migration process. Yet, there are several significant differences among its versions. 

In the Enterprise edition, users update their versions to the latest one with the official Odoo service. One should leave an application at the service desk and confirm the wish to migrate from the older version to the new one. The service desk would look at the application and ask the company to download the backlogs before migration. It’s vital to pay attention that the service desk supports a company for a limited time after the latest version’s release.

Besides, the Enterprise Odoo users should remember that a basic set of modules automatically migrates to the newer version. The company should check which modules can migrate and which ones should be repurchased or re-integrated to avoid setbacks. It depends on the individual module development case.

In case the company developed its customized modules and existing integrated systems with Odoo or the module logic was changed. In that case, it’s worth asking an Odoo developer if they can also migrate to the newer version or should the developer make some changes in the modules according to the latest Odoo version.

Odoo Community Migration

As for the Odoo Community edition, the client can perform the migration process by themselves by downloading a migration code for the latest Odoo version. Furthermore, the company can additionally integrate customized modules to the newest version. Yet it could be rather tough to migrate all the data smoothly without the support of a professional Odoo developer.

In Odoo Community, the process with the first two migration steps (analysis of the changes and upgrade of the custom modules) is the same as the Enterprise edition employs. However, the upgrade of the database can vary.

The Community users apply different modules, and the way they migrate may differ from each other. Some of them should be downloaded again, and some modules the company should purchase regarding the new version. So in many cases, it’s vital to find a trustworthy Odoo development team to solve all the arising issues. 

To Sum Up

Migrating Odoo to the latest version can be time-consuming due to a lack of experience with Odoo upgrades. Our specialists are always here to be concerned with your case, conduct proper research, and suggest the most acceptable migration strategy. Contact us for further information.
