The Deploy module is designed to allow users to easily stage content from one Drupal site to another. Deploy automatically manages dependencies between entities (like node references). It is designed to have a rich API which can be easily extended to be used in a variety of content staging situations.
Deploy is being re-designed for Drupal 8 and will be based on the Multiversion and Relaxed Web Services modules. This will create a very flexible and efficient content staging framework for Drupal 8! See the below presentations for more details:
The Drupal 7 version will see a complete rewrite to provide a more flexible API and workflow and to take full advantage of the new APIs in core.
We are heading for a beta release with some outstanding issues to deal with before we will roll. See the issue tag beta blocker and .
Deploy for Drupal 6 makes extensive use of the Services 6.x-2.x module for communicating with remote sites. (As of 07/18/2011, Services 6.x-3.x is incompatible, and there are no plans to make it so.)
Please read the installation and usage documentation before using the Deployment module. There are a lot of moving parts and while its not "hard" to setup, there are several steps to go through. Also, you can watch this screencast:
