The assertion was that switching vendors would save $10M. I asked why the new vendor would forego $10M that the old vendor was able to collect. Are you saying that the new vendor has to offer this discount otherwise there’s no incentive to migrate? (I agree that migrating is very difficult politically.)
So you did, I did not pick up that you meant peer vendors which is pretty obvious on re-reading. I believed you were saying that Enterprise Vendors (who are often Oracle customers) would jump to save $10m. But that wasn't what your question was.
