The figure is a documentation roadmap for using the Migration utility or the Oracle Data Migration Assistant.

If your current database is release 7.2 or 7.3, start with Chapter 1 of this book.

If your current database is release 7.1, check your operating system-specific Oracle documentation to see if direct migration to Oracle9i is supported. If so, start with Chapter 1 of this book. If not, upgrade to the latest 7.3 release on your operating system, using the book "Oracle7 Server Migration for Release 7.3," and then proceed to Chapter 1 of this book.

If your current database is release 7.0, upgrade to the latest 7.3 release on your operating system, using the book "Oracle7 Server Migration for Release 7.3," and then proceed to Chapter 1 of this book.

If your current database is release 6.0, upgrade to the latest Oracle7 release on your operating system, using the book "Oracle7 Server Migration for Release 7.3," and then proceed to Chapter 1 of this book.

NOTE: In any case, you should consult your operating system-specific Oracle documentation.
