I migrated a little endian format platform (Microsoft Windows x86 64-bit) database (Oracle 11g) to a little endian platform (Linux x86 64-bit) with RMAN. And also I did, that "Cross Platform Transportable Tablespaces Migration (HP-UX (64-bit) Big endian to Linux IA (32-bit) Little endian)" Here I have a doubt, that "Can't we migrate a little endian platform database to a big endian and vise versa with RMAN?".
