Pete,
We'll be going from an 800 to a new 520 (mostly likely) in about 4
months or so... i'm starting to look at the very same concerns.

Rob (and Vern),
After poking around in the info center it *seems* like Appendix D is the
answer. I am a little concerned about the "same OS levels" though. The
270 is running V5R3M0 with the latest CUME and group PTF's and I think
that the new i5 (the Power5+ hardware) is running V5R3M5 (LIC-not
sure). Rob, you had a post in February about an 8xx to 520 upgrade and
recommended loading LIC from the new system CD's and then loading the OS
from the SAVSYS tape of the old system (if I understood the posts
correctly). Would that be the recommendation in a 270 to 520 upgrade as
well? The only wrinkle from my perspective is getting the V5R3M5 CUME
and group PTF's in time since I know they won't be included in the
install media on the new i5.
Both the 270 and 520 have compatible tape drives so I may be able to
skip the install from CD and apply PTF approach and just restore from
tape. Correct?
Here is what I am considering (following Appendix D with the following
changes):
1. SAVSYS on the 270 and new 520
2. IPL the 520 from the 520 SAVSYS and install the LIC
3. When it comes time to install the OS, swap tapes and install the OS
from the 270 SAVSYS
Other steps in Appendix D remain the same.
Is this a solid approach or should I look at alternatives?
Thanks.
Pete
