Hi,
To compare Odoo v17 and v19 features, especially for inter-company transactions, multi-currency, and exchange rates, start with the official Odoo documentation, release notes, and community blogs. These resources often highlight key changes and improvements in each version. For a hands-on approach, use Odoo.sh to create a staging environment and test upgrade a copy of your Odoo 17 database to version 19. This allows direct feature comparison without affecting your live system.
Alternatively, set up separate test databases for both versions and manually compare the functionalities you're interested in. If you need expert insights, consider consulting with an Odoo partner. For inter-company transactions, check for improvements in automation and reporting. For multi-currency, look at exchange rate handling and reporting options. For exchange rates, see if there are enhancements in automated updates and historical data tracking. If you use Odoo Studio, ensure your customizations behave correctly in both versions.
Hope it helps
