Updating OS on Unsupported Macs

I have seen postings on YouTube regarding upgrading your OS on unsupported Macs. I have 2 Macs, a MacBook Air 2011 and an iMac 27" i7 2011. Has anyone upgraded their OS to Monterey. Are there any caveats? Have you been successful? Should I just leave my Macs as they are?
