Thread:Project:Support desk/Upgrade from MW 1.18.1 to 1.23.5 left duplicate users with Uppercase Uppercase rest lowercase USernames and now apparently standard Uppercase rest lowercase Usernames./reply (3)

Renamed in Database: USername to U1ername.

Merged: U1ername to Username, with success.

Can anyone tell me if this will either break anything or leave orphaned records?

Thanks.
