The following is what I plan to do, I would like to know if it is correct and is there anything wrong with my understanding?
1. Declare a new domain, add domain and change settings
2. Update the email address of a single user and test the new account login.
If the single account test is normal, you can use the sample file to update a large number of users.
The "UserEmail" field in the sample file remains unchanged and must contain the current user's email address.
In the "UpdatedUserEmail" field, enter the email address for the new domain.
Once the import is complete, the user's email address will be updated.
All existing information will be there.
※ It is recommended to set up and test SSO in a demonstration organization first. Once successful, repeat the same steps in the production organization account.
Login to different URLs will lead to different environments.
