Cross Platform Migration An Unproblematic Approach (Windows-UNIX ) Oracle 10\11g
The principal restriction on cross-platform transportable database is that the source and destination platform must share the same endian format.
Redo log files and control files from the source database are not transported to destination database . New control files and redo log files are created for the new database during the transport process, and an Open Resetogs is performed once the new database is created. BFiles, External tables and directories are not transported.

The following directories exist in the database:

PL/SQL procedure successfully completed.

Now the database is ready for transport , make sure as to where you are going to convert the datafiles.You may choose to convert the datafiles of the
database being transported on the destination platform instead of the source platform.
in the source database connect to target catalog
RMAN> connect target /

2> CONVERT SCRIPT 'C:\convertscript.rman'
3> TRANSPORT SCRIPT 'C:\transportscript.sql'
4> new database 'ORCLWIN'

Run SQL script C:\TRANSPORTSCRIPT.SQL on the target platform to create database
Edit init.ora file C:\INIT_00JGMNV5_1_0.ORA. This PFILE will be used to create the database on the target platform
Run RMAN script C:\CONVERTSCRIPT.RMAN on target platform to convert datafiles
To recompile all PL/SQL modules, run utlirp.sql and utlrp.sql on the target platform
To change the internal database identifier, use DBNEWID Utility
