We fully understand that things often are
complicated and mission critical
7

And things can become really complicated ...
 Oracle 8i to 11.2
 26 TB
 Oracle EBS
 5-6 hours max downtime
Good luck!!!

Or more work ...
 Triple hops ↘ Oracle 9.2.0.1
↘ Oracle 9.2.0.4
↘ Oracle 10.2.0.5
↘ Oracle 12.1.0.2

Don't maintain a zoo!
 135 Oracle databases
– 7 different Oracle releases
– 13 different Oracle patch levels
 6 different OS vendors
– 15 different OS versions
2% of all databases
under bug fixing support

Why people usually don't upgrade?
"You need to upgrade
now as your release is
out of Premier Support
already!!!"
"Upgrading just
costs a lot!" "I don't see any benefits by
upgrading to a newer release"
"It will just introduce
new bugs and issues"
"I'm happy with the
features of Oracle 8i"
11
"We'll wait for the
2nd release only"
"Application is not certified"

Anja Albrecht, Rechenzentrum der Finanzverwaltung NRW
"The migration of all 16 German Electronic
Income Tax databases to Oracle Database 12c
in less than 10 months went smooth and fine.
We are very satisfied with the performance
