Merge Duplicate User Accounts
From the left navigation menu, click Users => User Merge. The User Merge page consists of two fields, each providing a user picker. Both the "Old user" and "New user" accounts must be active and assigned the “Student” role to qualify for merge.
This feature is not designed to modify inactive or administrative accounts. However, there are workaround options. Administrative user accounts can be merged as long as they include an active “Student” role. Inactive accounts can only be merged after the user is reactivated in the system.
