Michael, Not sure, but form past experience moving from 32 to 64 bit all you needed to do was run catproc thereafter to recompile everything properly. But, and someone correct me if I'm wrong, I believe rman can only migrate database files across systems with the same endianesses. Namely big to big and small to small. I believe there's a package/procedure in the database that tells you if the move is supported.

I think that exp/imp is your only option.

What are my options besides exp/imp (datapump)? Source: Little Endian - Microsoft Windows IA (32-bit) Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 Target: Big Endian - HP-UX IA (64-bit) Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 I think I could tranport user tablespace but not the entire database.
