You must install some migrated definitions in the system when you initialize it. You do this by means of a list named in the GRPLIST system initialization parameter. The MIGRATE command created groups of resource definitions. You must create a list by using the ADD command to add some of your groups to it. For more information about this, see The CEDA ADD command. You can choose a name for the list: you specify this name in the GRPLIST operand.
To start off with, include a group containing a definition of a terminal that you can use for RDO: to create other lists and groups, and to install other groups of definitions in the active CICS system. To enable you to use RDO, include in your list the CICS-supplied definitions for the resources RDO itself uses, and for the resources used by other CICS-supplied transactions, including CEMT, that you want to use. The easiest way to do this is to use the APPEND command to append the list called DFHLIST to your own list. For more information about this, see CICS® Operations and Utilities Guide.
