This illustration is a graphical representation of the migration of an Oracle database from an Oracle Cloud Infrastructure Classic shape to the later Oracle Cloud Infrastructure shape. On one side, the database resides on Oracle Cloud Infrastructure Classic, where the database can be Oracle Database 11g (11.2.0.4), Oracle Database 12c (12.1.0.2 or 12.2.0.2), or Oracle Database 18c (18.1). From there, using the ibkup utility, you migrate the database to Oracle Cloud Infrastructure.
