I wasn't happy with how my skin was looking, so I backtracked to that just to see if I missed something or could make it look better. Tweaking around the Random Walk Skin, I found a scale of around .005 - .002 roughly seemed to produce similar results for me as Random Walk in his version, though I'm not sure if that's because of my thickness in places where he might have been a bit thinner in his sculpting or if it's due to changes in how the values work for that particular method. I was trying the "skin" one because that's the one that's supposed to be designed for skin. Based on the video I linked, I do have a IOR of 1.4 (which I think is the default) and a Anisotropy of .8 (which is the recommended value for human skin).
You can never blindy Copy/Paste Values from a Tutorial, but this is especially true for SSS. You can use them as a starting point, but even if you end up with drastically different Values, that doesn't mean that something's wrong, or that it's because you're using a different Blender Version.
You can create a simple test file in the older Blender Version and then open it in the new Version. See if it looks the same (it should) and if and how the Values in the Node have (automatically) been changed.
