It's called "rollout update". Here's a quote from the WAS InfoCenter describing it:

After the application file or module installs successfully, do the following:

If a changed application or module is deployed on a cluster, roll out the changes to all cluster members of the cluster on which the application or module is deployed. Click Rollout Update on the Enterprise Applications page to propagate the changed configuration on all cluster members of the cluster on which the application or module is deployed. Rollout Update sequentially updates the configuration on the nodes that contain cluster members.

Tip: At the end of the Installing messages displayed by the console during application or module installation, click Manage applications to go to the Enterprise Applications page. Do not save changes to your configuration until after you roll out the changes.
