1. A computer system comprising: at least one processor; at least one memory unit coupled to the processor having stored thereon instructions which when executed by the at least one processor, cause the at least one processor to: determine whether to define a new secondary access channel based on an existing primary access channel, the primary access channel being configured to be accessed by a set of one or more device types and the secondary access channel being configured to be accessed by a set of one or more different device types; in response to a determination to define the new secondary access channel based on the existing primary access channel, access data defining a user experience that includes multiple user experience attributes, a portal that includes multiple portlets, and content management that includes a content management attribute, for the primary access channel; determine characteristics of the set of one or more different device types to access the secondary access channel; automatically identify aspects of the user experience, the portal, and the content management for the primary access channel as either appropriate for the secondary access channel or inappropriate for the secondary access channel based on applying a set of stored mapping rules to the characteristics of the set of one or more different device types to access the secondary access channel and the data defining the user experience, the portal, and the content management for the primary access channel; automatically determine multiple recommendations for migrating the primary access channel to the secondary access channel based on the aspects of the user experience, the portal, and the content management for the primary access channel that are identified as inappropriate for the secondary access channel, where each of the multiple recommendations indicates one or more of that a particular user experience attribute included in the user experience of the primary access channel is inappropriate for the secondary access channel, that a particular portlet of the portal of the primary access channel is inappropriate for the secondary access channel, or that a particular content management attribute of the primary access channel is inappropriate for the secondary access channel; output on a display the multiple recommendations for migrating the primary access channel to the secondary access channel to assist in defining the secondary access channel; receive a user input indicating which of the multiples recommendations output on the display are accepted by the user; in response to the receipt of the user input indicating which of the multiples recommendations output on the display are accepted by the user, define a user experience for the secondary access channel based at least on the user input and to enable mapping of the user experience defined for the primary access channel to the user experience for the secondary access channel and to adapt the user experience for the secondary access channel to the characteristics of the set of one or more different device types to access the secondary access channel; define a portal for the secondary access channel based at least on the user input; define content management for the secondary access channel based at least on the user input and to customize presentation of content for the secondary access channel; and configure the secondary access channel based on the defined user experience for the secondary access channel, the defined portal for the secondary access channel, and the defined content management for the secondary access channel such that the set of one or more different devices access the secondary access channel.
