A successful upgrade ensures that the user is get the maximum benefit from the new features, security patches, and the performance enhancements while preserving your tailored business logic.  

In this blog we will read about the process of upgrading a customized database, focusing on the best practices, learning about the step-by-step procedures, and the essential considerations. 

1. Assess and Plan Your Upgrade

Comprehensive Backups: 

Before any upgrade, it is essential to create a full backup of the users production database and the file store. Store the backups securely and verify their integrity just to ensure that they can restore their system in case of any project failure. 

 

Backup Testing: 

Test the restoration process on a separate environment as it confirms the backup’s reliability. 

 

3. Prepare Custom and Third-Party Modules 

Code Review: 

Review all the custom and third-party modules for compatibility with the target version. Odoo’s APIs and data models may change, requiring the elements like code updates. 

 

Update and Refactor: 

Update the custom modules in such a way that it get align with the new version’s standards. Refactor the deprecated methods, update the views, and adjust the overall level of security rules as per the need.  

 

Testing on Clean Database: 

Install the updated custom modules on a clean instance of the new Odoo version. And verify the installation process and basic functionality before the actual migration of the real data. 

 

4. Set Up a Testing Environment 

Clone Production Database: 

Create a clone or a similar interface in simple words of the users live database and deploy it in a staging environment. This sandbox allows the Odoo expert team to run the upgraded process without any risk related to the production data. 

 

Testing Infrastructure: 

Ensure that the testing environment mirrors the users production setup completely, including the server configurations, integrations, and the user permissions. 

 

5. Execute the Test Upgrade 

Upgrade Tools: 

Use the official Odoo upgrade tools or the platforms like Odoo.SH Upgrade or upgrade.odoo.com as to process the users database dump. These tools further automates the much of the schema and the data migration, but customizations may also require the manual intervention. 

 

Iterative Testing: 

After the initial upgrade, it is important to thoroughly test all the business processes, check the custom workflows, and integrations. Document all the issues and iterate this helps in fixing the bugs, re-test, and repeat it until the system is stable. 

User Acceptance Testing (UAT): 

Involve the different key users as to validate the upgraded system. Their feedback ensures that the critical business operations are functioning as expected. 

Best Practices and Common Pitfalls 

Test Early, Test Often: 

Testing is the most important phase hence it is advisable to use a dedicated team that test the user business environment and involve the real users in UAT as to catch the various issues before the user reach production stage .  

 

Limit Downtime: 

Schedule the upgrades during the off-peak hours and keep the main users informed to minimize the chances of operational disruption. 

 

Document Everything: 

Maintain a detailed documentation of the services like customizations, upgrade steps, and issues encountered. This aids the chances of troubleshooting and future upgrades. 

 

Engage Experts: 

Consider the partnering with the certified Odoo professionals or the migration specialists, especially when it comes to the heavily customized databases. 

 

Monitor Post-Upgrade: 

Closely monitor the system after it goes-live. Be ready to roll the back to the previous version if there is any critical issues arise.
