If you’ve gone live then it’ll be difficult to change things, though the original username should be in a user custom field. You really want to solve these problems in the testing phase.

Unless the migration script is broken, the reason that usernames are changed is that they are incompatible with the discourse username format.

What are some usernames that were changed? What did you migrate from?
