I have 2 custom modules (module_one and module_two)
In module_one, I have a boolean field module_module_two in res.config which will install the module_two
BUT when i upgrade the module_one, it returns an error " field module_module_two doesn't exist" then I tried to reinstall the module one and it works but I don't want to uninstall it cuz the data of the module_one will lost.
How can I fix this?
