How to Merge a New Event with an Already Merged Event?
Can I merge a new event with a previously merged event? So I have an event that was already merged with a different one, and now I want to merge it with one more

The knowledge sources don't explicitly address whether you can merge a new event into an already-merged event in Lexicon.
What the documentation does confirm is:
Merging in Lexicon combines events into a single logical event without affecting raw data. [Lexicon Merging Data]
You can unmerge a previously merged event, which restores the original two distinct events. [Lexicon Merging Data]
A possible workaround if direct merging into an already-merged event isn't supported would be to:
Unmerge the existing merged event back into its original two events.
Then merge all three events together at once into a single canonical event.
Alternatively, you could use a Custom Event to logically group all three events under a single name for reporting purposes, without touching the Lexicon merge at all. [Custom Events]
For a definitive answer on whether chaining merges is supported, I'd recommend reaching out to Mixpanel Support or checking the Mixpanel Community.

I got it to merge. Is there a quick way to update any references to the old event name?
kapa.ai is there a quick way to update any references to the old event name? I just got the three events to merge, but I am using the new event name and have a lot of reports that depend on the old event name that I’m manually updating. It would be nice if there was a way to quickly update all the reports
Unfortunately, the knowledge sources do not describe an automated way to bulk-update all reports that reference old event names after a merge.
What the documentation does note is that after merging events in Lexicon, you should manually update affected reports:
"After you merge an event into another, it no longer appears in reports or custom events that reference it. Update those reports with the new merged event to maintain accuracy." [Lexicon Merging Data]
This suggests the update process is currently manual. The governance guidance also echoes this: "Update related dashboards and reports to reference the new names, verifying that historical trends remain intact." [Govern Data]
One thing worth noting: the merge in Lexicon creates a logical alias, meaning both the old and new event names are recognized as the same event going forward. [Lexicon Merging Data] So reports referencing the old event name may still work correctly depending on how the merge resolved — it's worth double-checking whether your existing reports are actually broken or just showing the old label.
If you're looking for a faster way to audit and update reports, the Mixpanel MCP Server could potentially help — it provides tools like Get-Events, Get-Report, and Update-Dashboard that an AI assistant could use to programmatically identify and update affected reports. [Mixpanel MCP Server]
For a fully automated bulk-update solution, I'd recommend reaching out to Mixpanel Support to confirm what's currently possible.
