Deploy

http://drupal.org/project/deploy

The deployment framework is a series of modules which are designed to allow developers to easily stage Drupal data (both configuration and content) from one site to another. Deploy module will stage nodes and automatically manage their dependencies (users, taxonomy, nodereferences, etc.) to push them as well if needed.

The deployment framework is designed to have three parts that work together:

• Deployment API - This implements the concept of a deployment plan. You create a deployment plan and add objects to it which will be deployed (content types, views, etc.) When the time comes these items are pushed to a server you specify via XMLRPC with an API key. The data stored about each item is extremely minimal, relying largely on the implementers to implement object-specific knowledge.
• Deployment Implementers - Individual modules implement the deployment API to add the data they need to a deployment plan, and expose that ability to the front end. Currently there are three deployment implementers - Content Copy, System Settings and Views.
• Deployment Services - Services modules which contain the knowledge to receive deployed data and do what is appropriate on the destination server. There are two deployment services included in this package - Content Copy and System Settings. This package also uses the Views service which comes included with the Services module, but it requires the most recent dev snapshot of Services.

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 a several steps to go through. Check out the screencast for a demo!
