I've done about 6 tests now, I would not recommend you do this without a test first.

Possibly this is an issue after Content Ratings import (have already mention on Content ratings thread) but I get the feeling this may rather be a xenforo issue, as surely in both the list and in the members eaters we should see Reaction score, not just like count. In the list of top 5 reaction...
xenforo.com

The content ratings are already there as reactions when you upgrade (after disabling CR)
You will see all your old ratings as reactions, but must check the scores type are correct (all mine imported as neutral)

You must rebuild Reaction score cache and check Notable Members top 5 reaction score, both in the list and when you click into the user details. They should be the addition of all reactions with score points and should be the same, if not it is the cache and runs every 60 minutes.
