This article provides the steps for transition an existing Office 365 services for a Reseller or Customer account.  This article applies to accounts that are currently or previously registered with Office 365 either via direct subscription or under another provider.  If the account's domain has never previously been registered with Office 365, please refer to the Enabling New Office 365 Services article.


Please note that the transition will need to be authorized by a user with Global Admin rights for the existing Office 365 account.  We recommend that you have the Global Admin user credentials ready before proceeding with the steps in this article.

Once the transition process is complete, all transitioned users will appear in the User List.  User licenses can now be directly managed via the Reseller Control Panel. Licenses associated with a previous Provider will need to be canceled. 


Please note that the transition process will assign new licenses to each transitioned user under the CloudPlus CSP. The process can not cancel direct subscriptions or licenses issued by other providers.  Once the transition process is completed, we recommend the customer contact their previous license provider to cancel the old licenses.  Customers may be double-billed if they do not cancel their old licenses.
