unable to merge user

Marvin Daniels

We are going through a domain change. We're retiring two domains and migrating everyone into a new domain. All domains are validated and, to date, we've merged 930 users.

However, when I attempt to use 'Merge User' on myself, it fails. Initially I tried adding my new email address manually, with the plan to promote that email to primary, but it would not allow me to add as an alternate email, so then I invited myself and accepted at my new email address. I currently have two logins that need to be merged, but it fails with the error below every time, which is a message I haven't seen with any other users during this process.
