The typical unit of deployment is CALLED a project. There are two types of project deployment: 

• Complete - The ENTIRE project is deployed
• Incremental - Only changes to the project since the last deployment or some explicitly selected subset of resources are deployed.

Incremental deployment is additive only new and updated resources are deployed on the target system. Note that any resource that is DELETED in the project is not deleted from the target system. However, deleted project resources are also deleted from the target system during a complete project deployment.

Note: This behavior MAY be customized at import time. For EXAMPLE, alert destinations are defined in the production system by the production system operator, but these alerts do not exist in the development system. In such a scenario, you may not want to delete these alert destinations when you do a complete deployment of the project.
