will each update need to be removed and a new one installed?
I suspect that you have become friends with Android not so long ago .....
Packages from one manufacturer - are put on top of themselves. If the signature matches, then put it on top. If the signatures are different, then only demolition.
Specifically here - I will not say, but if you want to jump on versions from Opel,
and then to the developer / stable - it is only through demolition.
If you hang on a particular branch of the program, then with updates.
