I actaully brought up the new z/OS V1.9 system in our shared plex (5 lpars) 
with everybody sharing.

So I used all of our current files (ACDS CDS, HSM Files, CF files, and so on).  
The first IPL was perfect, I had no issues.

Only gotcha is that you need to do all your SMS work from the higher level 
operating system once it touches your SMS data sets.  But I had no issue doing 
the software upgrade and then just IPL'ing the system into the plex the first 
time.

Of course I made sure all the toleration maint between z/OS V1.7 and V1.9 was 
in place.

I even did a fall back from 1.9 to 1.7 without issue.

To recap,
 1)  Laid down the Software installation for Serverpac
 2)  Build the new SYSRES and OMVS data sets
 3)  IPL'd into the plex using all the current data sets for JES2, HSM, SMS, 
and so on.  The IPL was done from the BASE serverpac level, I have no problems 
to report doing that.
