"New Replacing Old" might be what they wish was happening, but in reality it's "old staying where it is and being joined by new in new market segments".
Oracle is still very much strongly entrenched in delivering quality to those who can pay for it.
The question I have is how many greenfield implementations of an Oracle database -- not attached to Peoplesoft or other applications -- have been sold in the last 5 years.
New is also replacing old in old market segments who use new technologies. Ask GitHub or Heroku or New Relic how much money they're making from people who also pay Oracle. It's got 8 figures in each case.
