ESCON to FICON Migration
When migrating from an ESCON CIP/CPA to FICON CNA-8000, the I/O Gen will have
to be tweaked to accommodate the FICON interface, but the existing VTAM XCA and
Switched PU gens can be used. The main difference in the I/O Gen will to use a FICON
CHPID in place of the ESCON CHPID and to use a UNIT=NOCHECK for the FICON
environment in the CNTLUNIT macro.
