Still getting the same error on migration, looks like the values are getting reset when taking the host out of maintenance mode in the cluster so I changed them after that and still, no dice.
I appreciate your help. I'll play with it a bit tomorrow and test it outside of the cluster. We going to start moving to 5.5 in a month, so this won't be a concern then, I just need a bridge fix until that time. It might be making a separate cluster out of these two hosts for the time being.
