I've been experimenting with feature version-ing and upgrading in Sharepoint 2010 and found a bunch of blogs, documentations etc. but it is still not very clear to me.
- How does Sharepoint store the feature versions? If I deploy more versions of a feature what happens to the old ones?
- When is update triggered, what triggers it, when does it do it automatically and when do I need to write code or update receivers?
- What should happen after the update with the elements that use the old feature (e.g. I have a content type with an element used by a list and I update the content type what happens to that list) etc.
Could someone explain all of this to me?
