Hi, John

You are correct; unfortunately there is no way to merge user accounts in Totara LMS. We did have a feature in our tracker requesting this functionality, however after some internal discussion it was deemed as unsuitable due to the technicality involved and potential risks in relation to data. As you can imagine and appreciate, overwriting data - especially when there is a lot if it to think about - is risky business.

You may be able to work around your issue by exporting completion information and reimporting it as a record of prior learning, however that would only really give you course and certification completion at a high-level and not any visibility of activity completion, performance management information, etc.

Merging of user accounts usually comes down to business process and I'd normally encourage people to look at the way accounts are currently setup. For example, would it be possible to map updated information to existing accounts via HR Import? ID numbers in HR Import provide a unique identifier and could be used to update account information, including usernames. For those accounts created via email-based self registration, it makes that task a little bit more difficult, although it could still be done via an import.

Does that help at all?

Cheers.

Tom
