“Regular” headaches turning into migraines?

Is it a thing that people who suffer from migraines don’t really have “regular” headaches anymore? Basically it feels like what would’ve been a regular headache in the past now develops into a migraine. Is that how this works? I know certain pain can trigger (or “become”) a migraine (like sub-occipital tension), so I’m wondering if all headaches just graduate into migraines for us lucky migraine sufferers.
