We have a student who was accidentally assigned a new ID in our SIS so when our Canvas SIS import ran that evening it assigned the student the new incorrect ID but all their enrollments are still referencing the former correct ID. We got the ID corrected in the SIS but not in Canvas.
I have tried to upload a csv with the correct former SIS ID but it says that ID is already in use. Although no active user has that ID. I also tried to manually update the login on the user account page but it won't take the former ID that way either.
Is there a way to purge the incorrect SIS ID from Canvas so it won't think it is currently in use?
