Could you perhaps have mean the z/VM Migration Guide (e.g. "z/VM Migration 
Guide Version 5 Release 4.0"  GC24-6103-07)?

Those migration guides contain upgrade changes going many releases back 
(for -07 all the way back to VM/ESA 2.2!). 

The chapters are (not to be missed):
Chapter 1. Introduction to Migration
Chapter 2. System Changes
Chapter 3. Changes to External Interfaces
Chapter 4. Migration Tasks
Appendix A. CMS Pipelines Message Cross-Reference [V2.3]
Appendix B. Sample Utilities for Converting to Configuration Files

At every version or release boundary, I'm always surprised <again> at how 
well IBM documents what has changed.
Migration (mostly of the directly) is difficult and tedious enough, 
without this manual it would be a lot worse.

There's usually a description of installing the "new" system 2nd level in 
CP
Planning and Admin. That's normally what I think of as the "upgrade" path.

Also, other places in IBM tend to have codified the n-2 support level, and
I'd suspect that the VM guys are also getting pressure to do that too. 
Mere
speculation, but...

I still have a good number of CMS users, so testing SPEs tends to be 
harder
for me in that I have to duplicate the entire scenario. I often find that
these days that the bugs are so subtle, it's easier to do the next release
and just leave 5.4 alone unless it's something that really breaks CP so 
that
you can't IPL. But YMMV.
