I want to ask about how to update Drupal 7 sites. My site is divided into 2 phases, after launching and adding data in the first phase, I now want to update the second phase. I have a lot of new content type, Views and panels. I added a new language and blocks, a lot of things. I can export panel and view but what about the content type, language and any permission or configuration that saved into database.
Use the Features module to export content types and permission. You can go to admin/structure/features/create and the select the features you want to export.
The Features module is your friend in deployment. However, there are some other things that are not supported by Features, and which require you to create an install script.
