In my first shop we did a conversion from OS/VS1 straight to MVS/XA (IBM made us an offer we couldn't refuse). This was a little before CBIPO so first had to lay down a starter system that was some flavor of MVS/370 or /SP. I say that because it ran under our VM/SP (actually HPO) system. Before we could start working on the MVS/XA system itself we had to install VM/XA which was in the process of being invented. The very first VM/XA for customers was VM/XA Migration Aid, followed as quickly as possible by VM/XA System Facility release 1 which was in turn followed about 6 months later by release 2. My boss and I knew all the VM/XA level 2 people by their first names. We definitely 'got' to do the stage 1 and stage 2 MVS gens once we got that far.
Looking back on it is fondly nostalgic but it was a constant pain at the time - but, boy oh boy, did we learn things! Good times. I don't think this helps the original poster much, but it did bring back memories Jim Horne -----Original Message----- ISTR there was also a special version of VM/XA made available "early" so that customers could run both 24-bit MVS/SP and 31-bit MVS/XA on the same physical machine. Peter I kinda remember MVS/XA and later ESA being CBIPO and CBPDO for maint. SYSGEN I think was still needed for XA and maybe ESA. I'm not sure what you meant by Optional Source Materials. If by that you meant optional source code to install, I think they went the microsloth bloat ware option later...
