Using Deletion Sets
You use deletion sets to identify those assets you want to delete from the target server during deployment. When you deploy the project, Deployer deletes the assets defined in the deletion set from the target server and then deploys assets defined for the deployment set from the source server to the target server. If Deployer does not display a server you want to use as a target, you have not yet set it up to work with Deployer. After you create a deletion set, you should identify the target servers from which to delete assets and then add the assets you want to delete in the deletion set.
You can also export deletion set definitions from one project and import them into another.
For runtime-based deployment, Deployer supports deletion sets for Broker, Integration Server, and Trading Networks assets only.
