In my previous post I shared some findings on migrating user and application data between platforms with different endianness, focusing on problems with reducing downtime.
Today I’ll talk more about the complexity of chosen method. It’s not only about complexity per se, it’s rather about the possibility to automate as much as possible in order to allow efficient migration of a big number of databases.

One can find a lot of sources and materials regarding migrating Oracle databases between platforms having different endianness, even though the choice of possible methods is limited in this case. On paper (slides?) everything looks fine, but then you hit bugs or environment-specific problems. Moreover, in real life the situation is always more complex than moving just one tablespace with just one datafile as shown in many places as an example. Today I would like to add my 2 cents into this topic, focusing on moving user and application data.
