Deployment Plan feature - The deployment plan lets an
administrator define specific features for a deployment in
an XML file, and re-use them for different deployment
types. For example, a production environment may have
specific database data source configurations that are
different from the test or development environments. The
master deployment plan for production will override or take
precedence over application settings for development
environment when deployed with it. This is very helpful
when administrators want to quickly deploy the same
application to test (qa) and production without any changes
to the app.

Side-By-Side deployment (Versioned Deployment) - The side-
by-side deployment or versioned deployment is an extremely
useful feature for updating production applications that
are live. It lets you specify a version (unique version
string entry in an Enterprise Application MANIFEST.MF file)
for an application and WebLogic will recognize that it
needs to deploy an additional application instead of
replacing the active one. This is most useful as a
production redeployment strategy; new incoming requests
will be directed to the new application version, and as
soon as all of the old sessions expire, the old application
(version) will be retired and deactivated.
