UPGRADE OR SYSTEM REPLACEMENT? 

I can only speak to the SYSTEM REPLACEMENT PATH, and it is about 60-80 hours 
(36 for install/test of CB/PDO (once received)) and 24 to modify the current 
environment  to use the newly created system. That is just for the install and 
migration. Does not include installing coexistence/fallback maint on current 
prod and also does not include exploitation of new features.

I'm not a sysprog and I'm trying to do a reality check on some numbers. What 
would the members of this august list guess would be the approximate number of 
work hours for an experienced z/OS sysprog to upgrade one LPAR from V1R13 to 
V2R1? No CICS, no DB2, just basic MVS, JES2 and RACF. Only a small handful of 
RACF users. Nothing "special." No application or ISV issues.
