 Hi,

What is the best way to step back in case of a database upgrade from 10g to 11g  (10To) under AIX 6.1 ?

1 / Restore from a logical backup.
2 / Restore from a physical backup (RMAN).
3 / Enable Flashback before the upgrade (restore point ?)
4 / Perform Oracle downgrade(SQL> STARTUP DOWNGRADE ...).

Avatanges and disadvantages of each method?

Do you know other techniques?

Thank you.

Howdy, Stranger!
