Impact of Merging Users with Non-Existent Distinct ID

Hi Lois, Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support. If you have follow-up questions for this thread, please tag me again with your question: @kapa.ai <follow-up question> 👋

I'm sorry, but the knowledge sources do not explicitly state what happens if you attempt to merge two users and one of the Distinct IDs does not exist in Mixpanel. The documentation describes how merging works and the requirements for merge events, but it does not clarify the behavior when a non-existent ID is included in a merge operation. For precise behavior in this scenario, you may need to test this in your Mixpanel environment or contact Mixpanel support for clarification.References: - Merge Identities – $merge event - Original ID Merge Mechanism
