Hi!
Please consider the following scenario:
I have a SP Project that contains a Package and a Feature. This package has been deployed and the feature has been activated already in a farm. Now I want to add a new Feature in the existing package and redeploy it in order to activate the new feature without affecting the old one.
I'm using Update-SPSolution to update the package in the farm but it seems that the new feature does not appear in the list of features of the sites. I read this http://sharepoint.stackexchange.com/questions/45675/how-do-i-update-an-already-existing-wsp-on-farm which suggests that if I want to add a new feature I need to uninstall and reinstall the package. But if I do that the old feature will be deactivated which means that data will be lost!
Isn't there any other way?
