Upgrading Odoo to its newer versions is crucial for businesses seeking to leverage new features, security enhancements, and improved performance. Although a successful upgrade can benefit companies, it can be daunting for organizations with complex, customized Odoo environments.
Through this blog, Confianz will guide you through the vital steps required to upgrade to the latest version of the Odoo ERP system. It will help your organization to be aware of the good practices, tools, and challenges faced during an Odoo upgrade.
Why is an Odoo upgrade important?
Odoo upgradation benefits your business with new enhancements that make Odoo faster and easier to use, boost productivity, and invigorate sales.
Confianz has elaborated on the reasons for an Odoo upgrade below:
Latest Features
As Odoo releases its newer versions, it brings fresh features and modules with new functionalities to streamline business processes.
Security Enhancements
An Odoo upgrade can ensure the system is protected with the latest security patches and improvements, reducing the risk of vulnerabilities.
Improved Performance
Each new release of Odoo is faster and more efficient because new releases often include optimizations to enhance the performance of the Odoo instance.
Support facility
Odoo’s official support facility ends after a certain period for older versions. On the contrary, using a newer version can render support from Odoo. Hence, the support facility associated with a newer version can help your company with updates, bug fixes, and support from Odoo.
Compatibility
Upgrading ensures that your system remains compatible with third-party modules, integrations, and external systems that may require updates.
Upgrade Process
Odoo Upgrade has a series of steps given below:
1. Pre-Upgrade Preparation
Here are four steps to follow for pre-upgrade preparation:
To assess the current Odoo environment
It is important to know some basic information about the current version of Odoo your business uses before starting an upgrade. This information includes identifying the current version your business is running, custom modules and third-party apps installed, and any integration that may be affected by the upgrade.
Release Notes Review Process
When your Odoo business software requires an upgrade, you must check the release notes of that version. It can help you understand the new features, changes, and deprecated functionalities that might impact your existing setup.
Backup of existing data
Before starting an Odoo upgrade, your company or the company helping you with an upgrade must take a backup of your Odoo database and file system.
Test Environment Setup
Set up a testing environment that mirrors your production environment. This environment will test the upgrade process and validate that everything works as expected before changes get implemented to your live system.
2. Analyzing and Adapting Custom Modules
One of the most challenging areas is custom modules to address for an Odoo upgrade. Customizations performed in older versions of Odoo may not be compatible with the newer version. The following three steps can help in overcoming compatibility issues:
Code Analysis
Reviewing custom modules can help identify compatibility issues as it helps in looking into the changes in Odoo’s API, deprecated methods, and new coding standards that may affect your custom code.
Refactoring
In this step, your company or any other company performing the upgrade for your business must modify the custom modules and ensure they are compatible with the latest version. This step may involve rewriting some parts of the code, updating dependencies, or adjusting configurations.
Testing
The next step is to test the custom modules in the test environment. This step will ensure that the custom modules work as expected with the new Odoo version.
3. Database Migration Process
Upgrading to a new Odoo version often requires migrating the database to match the new structure and schema.
Odoo Migration Scripts
Odoo provides migration scripts that handle most of the database changes required during an upgrade. These scripts ensure data gets correctly migrated to the new version.
Data Integrity Checks
After running the migration scripts, perform data integrity checks to ensure that all data has migrated correctly and that there are no issues with the database.
Custom Data Migration
Custom migration scripts may be required if you have custom fields, tables, or complex data structures to handle these during the upgrade. This step can ensure your custom data is preserved and functions correctly in the new version.
4. Performing the Upgrade
With the preparation complete, the next step is to perform the Odoo upgrade operation.
Odoo Enterprise (Odoo.sh)
Odoo.sh is Odoo’s Cloud platform that provides tools to automate the upgrade process, including running migration scripts and handling database migrations. You can initiate the upgrade directly from the Odoo.sh interface.
Odoo Community or On-Premises
If you are using the Odoo Community edition or an on-premises setup, the process for upgrade is as follows:
1. Stop the Odoo Service
Ensure that the Odoo instance is not running during the upgrade to prevent data inconsistencies.
2. Download the Latest Odoo Code
Download the new Odoo version from the official repository or the Odoo website.
3. Update Python Dependencies
Use pip to install or update the Python packages required by the new version of Odoo.
4. Run Migration Scripts
Execute the migration scripts provided by Odoo to update the database schema and data.
5. Start Odoo and Test
Once the migration is complete, start the Odoo service and test the instance to ensure everything functions correctly.
5. Post-Upgrade Testing
Testing is a vital step of the upgrade process and ensures that the new version of Odoo functions as expected. The testing phase helps to understand whether your business processes got disrupted after the upgrade process.
Following are the types of testing to perform on the new version of Odoo:
Functional Testing
In functional testing, all the core functionalities of Odoo ERP software are tested, like sales, purchasing, inventory, accounting, and many other modules relevant to your business. Functional testing can help you know whether all the workflows operate smoothly.
Custom Modules Testing
In this type of testing, each customized module gets tested individually to ensure that the customizations work correctly with the new version of Odoo.
Data Validation
This step verifies whether the data is migrated correctly. It can ensure no missing records, incorrect data, or inconsistencies.
User Acceptance Testing (UAT)
This step involves end-users in the testing process. This step ensures that the system meets your needs and expectations. UAT helps identify any issues during functional testing that may have been overlooked.
6. Go-Live and Monitoring
Once testing is successful, the next step is to perform the go-live.
Plan the Go-Live
Choose a time for the upgrade to have the minimum impact on your business operations. Typically, this is done during off-peak hours or over the weekend.
Final Backup
Next, a final backup of the production database and file system is taken before beginning the go-live process.
Switch to Production
The next step is to implement the upgrade in your production environment. It involves stopping the production service, applying the upgrade, and then starting the service again.
Monitor the System
After going live, closely monitor the system for any issues. Ensure that users can access the system and that all processes run smoothly.
Support and Issue Resolution
In this step, the support team addresses any issues that arise post-upgrade. Thus, having a support plan can help to resolve any disruptions quickly.
Best Practices for Odoo Upgrades
