Merging my DL and NW accounts was messy and I had issues of not being able to log in, incorrect information, etc, for a time. It did not harm me because I wasn't doing anything active with either account and my DL/NW flying was being credited to my YX account. But it took time to get cleaned up, and I would not be surprised to see similar in this merge.
As far as merging accounts, I can see potential problems such as registering with a middle initial for one account, but not the other, using a home address for contact info on one, but work address for the other, different contact phone numbers, etc.; it will be a major project!
For the NW/DL merge, there was an incentive of bonus miles for those FF members who voluntarily merged their two accounts, well in advance of the formal transition; this lightened the load at the end of the process for DL.
