UMS Gmail user wants to import UMS Google emails to their personal Gmail.
Instructions
There are several options for transferring the data in your UMS Google Account to a personal Google account.
Please see https://support.google.com/accounts/answer/6386856 for the details and guidance on the options.
The import process takes awhile, but since it's happening behind the scenes on the Gmail server, you don't need to stay logged in and baby sit. You can go about your day.
INFO: If you receive an error indicating that the transfer process is not enabled for your account, double check which account you are currently signed in to. It may be necessary to use a "private" or "incognito" browser session to ensure you are using the account matching the directions.
