The exact release of the operating system are (in theory) not affecting
the portability of datafiles. As long as

- operating system (Solaris, HP-UX, Linux...)
- CPU platform (32/64 Bit, SPARC/x86/HPPA...)
- Oracle Release

are the same, you should be able to just copy the files, because the
headers are identical in those cases. Reason: the Oracle-feature
"transportable tablespace" relies on that and defines the above criteria.
