The title says it... I recently changed my username. After having done this a couple years back and having my data migrated back then, and what I'm wondering is if a new migration is necessary. I'm unsure of how the system works nowadays and if I need a migration again. I also didn't take this problem into account this last time that I changed my name (because of it last happening almost 2 years ago) and am apologetic for this being a possible issue for any staff.
