Odoo POS Module Migration
by Hafiz Junaid
Migrating a Point of
Sale (POS) module from Odoo version 12 to version 16 involves several steps to
ensure compatibility with the changes introduced in the newer version. Here's a
general outline of the migration process:
Step 1: Backup your data
Before proceeding with any migration, it is crucial to create a backup of your Odoo 12 database and your custom POS module. This ensures that you have a safe copy of your data in case something goes wrong during the migration process.
Step 2: Update your custom module
Update your custom POS
module's code to make it compatible with Odoo 16. Odoo versions introduce
changes to the core system, and some APIs and methods may have been deprecated
or replaced with newer ones. Review the Odoo 16 documentation and release notes
to understand the changes and how they might impact your module.
Step 3: Update dependencies
Check if your custom POS
module depends on any third-party modules or libraries. Ensure that these
dependencies are compatible with Odoo 16. You may need to update or replace
them if they are not compatible.
Step 4: Review model changes
Odoo might have made
changes to the core models, including the 'pos.order' model used in the Point
of Sale module. Review the changes and update your module's code accordingly.
You may need to adjust the model's fields, methods, or constraints to match the
new version's requirements.
Step 5: Update views
Check the XML views used
in your POS module and ensure that they are compatible with the new view syntax
and structure introduced in Odoo 16.
Step 6: Update security rules
Odoo's security rules
may have changed, so review and update the security rules in your POS module
accordingly to ensure proper access controls.
Step 7: Test thoroughly
After making the
necessary changes, thoroughly test your custom POS module in Odoo 16. Ensure
that all the functionalities are working as expected and that there are no
critical issues or errors.
Step 8: Update the manifest file
Update the manifest file
of your custom POS module to specify the supported Odoo versions. Make sure it
includes "16.0" as a supported version. In Odoo 12 we added all
JS-related files in XML view and then added these files in the manifest. But in
Odoo 16 there is a slight change, we need to add all files related to js, scss,
and xml in the manifest file under their own bundle.
Step 9: Deployment
Once you have
successfully migrated and tested your POS module, you can deploy it to your
production environment. However, it's essential to perform a thorough test
again in the production environment before using it in a live environment.
Keep in mind that the
migration process may vary depending on the complexity and size of your custom
POS module. It's essential to carefully review the changes in Odoo 16 and adapt
your code accordingly. Additionally, consider seeking assistance from Odoo
developers or partners experienced in migration to ensure a smooth and
successful migration process.
