eBS: cross-platform migration on OCI with xtts

This note is about migrating a non-Linux eBS system, 12.1.3 to OCI, using the transportable tablespace method, as detailed in the MOS 2473448.1

This method is suitable for production-like environments, unlike the vision demo system which proved to be impossible to migrate using this method, the number of transportation violation being very large.

#2 Prepare the target dbsystem according to this note.

#3 Prepare the target compute according to this note.

#4 Execute the database migration.
