Onboarding of users via Stage

Onboarding of users via Stage

Hi,

I read somewhere that it is possible to onboard users through Stage, and they can upgrade into Production. Have I understood correctly?

I have a customer which I placed in Stage due to a temporary problem in publish to production, now this is fixed, and would like to just upgrade them direct into production from Stage rather than creating a separate account and migrating the registers manually.

I can see that the option to upgrade is there, but just hoping that this will take the customer into production, not a paid account in Stage?

Thanks
Karen
