Not entirely related, but when I was migrating from VB I started by telling people in advance to flag any accounts they wanted merged. Then I manually fixed all accounts with duplicate email addresses on a SQL dump of the VB user table... some people had 3 or 4 or more so it took quite a while, but meant i could identify their "main" account and keep that associated with their actual email address (most of the additional ones were joke / disposable usernames that had only been used a handful of times). Doing it by hand also meant that any secondary accounts registered to a single gmail address could be changed from user@gmail.com to user+accountname@gmail.com and they'd still get notification & password reset emails etc.

My progarmmer just add the ID number to Email.
for example, my ID is 100315 and my Email is fingon@fingon.com, then I change email to 100315fingon@fingon.com.
with this no one has same emails
