I have 3 different environments such as Dev, Test and Stage. I'm currently facing an issue when trying to propagate my changes from Dev into Test and Stage envs. In order to propagate the changes i use the Features module. Within features i export all my Content Types. Some of them (e.g. Basic Page) are already exist into Test and Stage environments. When i'm trying to install the feature export from Dev into the other environments, the Basic Page content type of Test and Stage actually seems to be overridden. This means that the predefined fields that already has are not erased by the feature but it just adds the new created fields. How can i solve this issue. The desired functionality is to have the same fields after importing the future to all environments.
If I'm not mistaken, Features doesn't delete fields it only synchronizes the configuration and creates new fields if they are not present. So, deleting obsolete fields is one of the processes you have to do by hand (or write an update function in a custom module).
Features is a handy tool, but certainly has some limits (for instance when you want to synchronize blocks).
I believe 1 approach using features do manage your setup like your doing is to use
hook_update_n() to delete fields you no longer want in versions of your module. So some tidying up code is in an update function assure only the fields you want in your content type exist at a certain version.
