Recovery options
The “Recovery Options” screen is a central piece of the migration in the author's opinion. Here you determine
your back-out-while-not-losing-face strategy. You can chose from any of the following three:
•
Backups managed with Recovery Manager.
•
Use of the Flashback Database feature for databases beginning with 11.1.0.7.
•
Your own.
If you chose to use an existing backup then please make sure it is current and includes all relevant archived
redo logs! You should also ensure that all the backup pieces are actually available if needed. If unsure, you could let
RMAN create a backup for you. To use Flashback Database your source database must be 11.1.0.7 or later, and the
Flashback Database feature must be enabled, otherwise you will see the option greyed out in in the screenshot. If you
opt to use your own backup strategy, then please have one that is tested and valid. Choosing this option is like telling
the Upgrade Assistant: “trust me, I know what I am doing”. The backup and possibly restore operation will be your
responsibility.
Finally it is time to start the actual migration! Another click on the “Next” Button will present you with a summary
of operations shown in Figure

below.
