Purpose ======= Even if the routes are correctly updated and the existing data is correctly updated, the emails that were already sent to the customers will be problematic, as we will provide a value which is not handled anymore (10 for example). To provide a retrocompatibility, deprecated the old route and introduce a new one. closes odoo/odoo#46296 Taskid: 2083096 Related: odoo/upgrade#889 Related: odoo/enterprise#10312 Signed-off-by: Yannick Tivisse (yti) <yti@odoo.com>
