Scenario: You decided to move your company (and all of your users) from Google to Azure.
You would assume that as an Admin, you could bulk migrate all of your users, but you can't. Don't ask why, I am pretty sure Atlassian themselves don't know why.
Every user will have to migrate themselves, and work through Atlassians "not bugs but features" bugs.
- Log out and log back in using @<your company>.com email address & password combination. If you don’t know, reset your password for @<your company>.com address.
- After you know your password, proceed.
- Log in using Username / Password combination.
Next: Update your email address to different SSO
OPTIONAL: While you’re here, why not use the Email Preference Center to unsubscribe from marketing emails?
Enter your <new email address> in the box and save your changes.
You will get confirmation email in your <new email> inbox.
Open the email, click the link, and you’ll taken to the login in screen showing your <new email address> account.
Use your <new email address> and old password.
THIS IS CRITICAL and a massive source of pain (which is "behavior as expected" according to Attlassian.)
If you don’t know your password, stop, log out and go to step 0. Resetting password here will create the new account, and you’ll have to go to troubleshooting section.
Last: Connect to Azure SSO
Super duper important (otherwise you’ll create additional headaches for youself): Review your Atlassian profile to validate that your email address has been updated to <new email associated with Azure> (https://id.atlassian.com/manage-profile)
Log in using "Sign in with Microsoft" button
You will get an email in your new account with a long string of numbers.
Enter it into the prompt and you're done.
Now under your "Email" page in Account settings, you will see a banner that reads "Your account is connected to a Microsoft account. Changing the email address here will disconnect your account from the Microsoft account."
Final: If you’ve ever posted in the Atlassian forums, you will get another confirmation email with a link to approve Forums email address update.
Q: At confirmation screen: you don’t know the password for your <new email address>
A: This is actually the password for your <old account> account. Attlassian claims it's not a bug
Once that's done, and your desired email address gets freed up, and you can attempt to switch address to Azure SSO again using steps above.
After successful switch, log into the extra account, and delete it from "Account Preference" page (https://id.atlassian.com/manage-profile/account-preferences). it’ll take 2 weeks.
