OK, I know no one here has the definitive answer to this but I thought I would through it out for discussion.
2 sites (A and B, both had manual penalties removed by submitting disavow files and reconsideration requests.
We are merging (301) site A to site B. In doing this whatever authority, links, and traffic the goes to A will now go to B.
But, but, but, site A's disavow file, does that transfer to site B, I don't think that it would. Could that be an issue for site B? Should site A's disavow file be merged with site B's at the same time site A is 301'd to site B?
