We have a fair bit of code in production that was written over 20 years ago. It just works. It has gone through strings switching from 8-bit to Unicode (16-bit) with hardly any modification.
We upgrade every year or so, and in almost all cases it's smooth sailing.
Delphi has been quite good so far when it comes to long term maintenance.
First they deprecated the bundled DB bindings, after hyping them to hell and back; then the bundled report generator. We had more than a million lines of code depending heavily on those.

Not my experience.
