RE: pa-risc to itanium migration

I've done several of these in the last few months (and will be doing lots more). The only real gotcha's I've run into so far involved attempting to upgrade from prior versions (8.1.7 and 9.2.0) to 10.2 at the same time I'm migrating. Other than that, it's been remarkable smooth.  

The executables are different and will have to be re-installed on the itanium based servers, but the data files are binary compatible.  

I've done both hot-copy clones and cold backup clones from PA-RISC to Itanium and got both to work (although I'm not sure the former method is supported)  

I didn't have to adjust any init.ora parameters other than the ones needed for the version migrations.

Good day all,  

I would appreciate hearing of any experiences of Oracle database migration from HP-UX PA-RISC to HP-UX Itanium, especially relative to Oracle spincount, cursor sharing, HP-UX config, and any other lurking gems.  

Environment:  

Oracle: 9.2.0.7 EE, OLTP avg sustained connects: ~3900

HP PA-RISC: HP9000/800/rp8420, 14 cpus, 48877mb, os: 11.11

HP Itanium: rx 7640, 12 cpus, 49017mb, os: 11.23

SAN: EMC, 1GB interconnects, single NIC    

Thanks.
