If you have a query with criteria set to pull a specific application user —for example, the criteria is "Application user is equal to [username]" — you may need to update the query to pull the application user's new username. (The new username is their Blackbaud ID email address.)

If you need to pull data about the user from before the upgrade and after the upgrade, you can change the query criteria to include the old username and new username — for example, the criteria would be "Application user is one of [old username] AND [new username]".
