Anything special to migrate from z/800 to z9 ?

Starting with z990/z890, there is no longer basic mode and the I/O
configuration changes drastically. You now have the CSS layer and must
configure PCHIDs and map CHPIDs to them. In addition, we were unable to
copy our image profiles etc. from the SE on the z800 to the SE on the
z9. I'm not sure if that's still an issue.
IMHO it's as simple as moving from z/800 to z/900.
The only trick is to "copy" current config from CPC to LCSS.
PCHID-CHPID mapping is an advantage: you can stay with your CHPID
numbers unaffected, simply map them to proper PCHIDs.
AFAIR I did new IODF (moving from z/800 to z/990) within 2 hours.
(the above is the proof: it cannot be complicated - I did it <vbg> )
Reset and Image profiles on SE - well, it's so easy to setup so I simply
never tried to use copy method. Of course YMMV, especially when having
many LPARs
BTW: OSA config is another story - it is not kept in IODF. Precisely it
depends on CHPID type. For OSE you have to clone your OAT, for OSC you
have to clone your session definition. The last one is AFAIK unavailable
on z/800 (I can be wrong), however can be easily moved (via txt file).
For OSD chpids only HCD definitions are to be moved.
