An incremental installation involves adding or modifying features of an existing installation without replacing or modifying the underlying WebSphere® ESB installation.
An incremental installation involves using a customized installation package (CIP) to add features to the current WebSphere ESB installation using a CIP which contains the same maintenance level of WebSphere ESB.
The result of an incremental installation is to leave the maintenance version of the product unchanged while adding or upgrading other features of the installation.
