How can we update the user name (from user@domain1.com to user@domain2.com) for all users that an application is already assigned to?

Due to a merger and name change, my company has added an alternate UPN to our domain.  As a result, users' Okta logins have changed from user@domain1.com to user@domain2.com (the alternate UPN).  This is working properly.  My question is, for all of the users that already have a particular application assigned to them, how can we change their user name from user@domain1.com to user@domain2.com without having to manually change it individually for each user?  I have tried unassigning the application from the group and then reassigning it, but that hasn't worked.

Hi Scott,

Thanks for reaching out to Okta Support Community Portal.

Based on your inquiry, you can leverage the Universal Directory (UD) feature by overriding the appUsername in Profile Editor or using Attribute Level Mastery (ALM) --if the alternate UPN is sourced from different directory/or master.

Okta Admin Dashboard > Directory > Profile Editor > select your appInstanceName i.e. Generic Radius App

Below are a few of articles for your references:
