Yes... using DDM

You don't need a Advanced S/36 anymore, ANY risc 400 can run dual
systems..

You can do that, but all external files will be on the OS/400 "side"..
and will be accessed using DDM.

OCl can be a problem to convert, since it's operational methods don't
make the most effective use of the AS/400...

Running in the S/36EE is an excellent way to take the customers over
in a gradual approach.. From a performance standpoint, you lose some
things, but not enough to really hurt you... MOST programs and OCL will
run without ANY changes, but there are performance considerations that
will improve the run times 1000%, which are VERY minor changes. What are
your concerns about the S/36ee ?? Using the S/36ee allows you to use ALL
OS/400 options and MOST S/36 features... There really isn't a "down"
side
to this approach...

If you "must" keep SSP, that will work also, but the administration gets
a little tougher keeping all the operational aspects of two different
systems in "sync". Not difficult, just more work..

Yes.... several times.... using "both" methods..
