RE: CISC to RISC Migrations

From my experience, don't upgrade but replace.  Buy the new box with a new
license and serial number.  Call all your venders and get there latest RISC
versions.  Re-create all your user profiles and directory entries.  Then
configure the two machines to talk to each other.  Finally write a program
to convert your data from the CISC machine and old software to the new
software versions.  Use DDM to read the CISC and write locally on the RISC.
Now your venders may have the update programs to convert the data files
which you can save/restore/convert.

Last step is to move all the hardware from the CICS to the RISC.  This gives
you the cleanest new RISC system possible.  OK I know I will be flamed for
this approach, but our CICS to RISC was done poorly and I spent months
cleaning up garbage from the restore.

Your other option is to read the road map for CICS to RISC and follow very
carefully and closely.  DO NOT skip even the smallest step.

Good Luck,

If anyone have any current information, issues or experiences that 
they would like to share regarding CISC to RISC migrations, please 
forword them to me.  My last migration I performed was a few years 
ago.  Looking for updated information, plans, etc...

Thanks,
