Help for RJE configuration requested

I have never configured RJE before.  I have only added entries to the forms
control table.  We are migrating from a CICS machine (9406-300) to a RISC
machine (9406-S20).  Can someone give me some guidance or tips on where to find
the all of the components for my RJE configuration and how to duplicate this on
the new box.  I don't even know what manual to begin searching for this
information.

We use this RJE configuration to pass data between our VSE/ESA mainframe and our
AS/400.  I can retrieve the source for the line, controller and devices on the
line and use this to define these definitions on the new box, but I do not know
what other components are required or how to find them.
