Hi
I have had experience with OGG, very good, virtually no downtime (in my
case was aprox 5 to 10 minutes in several migrations). You dont need as
much as preparation as TTS but there are preparations specially migrating
from old 9i to latest versions.

But you need a lot of $$$ to buy OGG because you have to license both
source and target systems. I have a few customers had to use other ways
such as TTS because of the license costs, you cannot buy OGG just for
migration purposes, if the customer cannot find a use for OGG after the
migration then they need to seriously considering if it's worth it.

Thanks
