Good afternoon, I'll explain I'm upgrading odoo sh from version 14 to version 15, my problems are because of the custom modules that are currently in version 14, I already have the repositories with their modules in version 15. It happens that in the instance of Production and testing has been going on for more than a year with the modules in version 14, so using the ssh key I am adding the submodules in version 15 and loading it in test, when reviewing the list of applications I updated it and the modules in version 15 do not appear. They maintain version 14, is there something wrong that I am doing? Is there an upgrade guide for Odoo sh but in a complete way, including an example of a repository or custom module, if in case I already have the code ready and just upload it to your test instance without affecting customer information?
