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.
