Thanks, Sam. The part I wasn't able to find on my own was that the 64 bit boxes can't be made to run in 31 bit mode w/o the migration offering.
Rex z/OS Bimodal Migration Accommodation offering http://www-03.ibm.com/servers/eserver/zseries/zos/installation/bimodal.h tml? ca=zos14&me=w&met=bimodal If you don't have it and you IPL your z/OS R4 on a 64 bit capable processor you will test 64 bit compatibility of your software for the first time at DRP. There is nothing your DRP provider can do with the hardware to put it in 31-bit only mode. Search the archives on "Bimodal" for discussions.
