I am developing a UWP application that is using the sideloading feature to install and update the application. My company recently got a new code signing cerrtifcate since the old one expired. With the new certificate some of the entries in the certificates subject field changed and with that the package family name.
That means that when I publish a new version of my app I get a prompt to install instead of update and a new independent instance of the app is installed. My main problem with this is the data that is stored in the apps local state folder that in my case contains settings and user generated data.
Is there any way to get around this problem and update my existing app or migrate the data of the old instance to the new?
