2 old sites are parked domains

I have converted 2 old websites to a new one. I was using CleanTalk for each of the old websites. The old sites are now parked domains or aliases, which are both redirected to my new website.

Since the old sites’ pages are not directly accessible, since they all point to the new website, is it suitable to discontinue monitoring of the old sites?

I will still use CleanTalk for the new website, but I don’t want unnecessary coverage.
