Hello everyone, 
I really need help in this process that is apparently easy, I have some custome modules that I uninstall from my main database because I don't need it and they are not compatible with Odoo16, I uninstall them after I delete and after that I delete from my github repository, the modules are completly eliminate from every part, but when I create the staging branch (without the custom modules) and I upgrade to 16, the process didn't end well becasue the system install my custome module eliminated, I try a lot times to try this works but nothing works, anyone could help me? what am I doing wrong?
