My understanding is that you can restore backup from any platform of same
endian-ness onto any other platform of same endian-ness and you don't need
to worry about RMAN CONVERT command. So all your normal migration options
should apply... data copy with rman restore or transportable tblspc, sync
with incrementals or logs (standby/data guard or goldengate/dbvisit), etc.

I think "cross-platform" in the oracle docs usually implies different
endian-ness. You probably don't need this.

Some migration methods should not require a second IA64 system for
testing. For example, if you just restore from the backup server then it's
possible to do the whole thing without *any* connection to the primary
database server at all. You can test that as many times as you want and it
should only put load on your backup system, not on the source server.
