How to do email Domain Change?

[twoods450]

My company was acquired, we just migrated email domains, but need to update all user's email addresses so they can use google auth to sign in. I can't modify emails addresses as an admin. Any simple solution?

 Why can you no modify the email addresses yourself?  Admins have that power.  You should be able to go to Settings->Users, click on user name, replace the email address, and click Save.  Repeat for each user.

For a large number of users, use the authentication/users and authentication/users/{name} REST APIs in a script.

I guess I should have said, this is in SignalFX, the email fields are all grey'd out, I'm not seeing a mechanism to update them.
