Just not that straightforward in practice. You have all of these product lines that people are building that you're hoping will grow the business. They all depend on your backend stuff that's just an implementation detail. You have to somehow convince everyone across the org to stall their product development to perform a "migrate to Postgres" thing? It's not going to be easy.
There was a recent big company that posted on Twitter about "shutting down our last Oracle server" and that was the last thing in a multi-year process or something like that.
Coordination is sometimes harder than the technology itself.
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.
