Hi @Fernandes Filho Fernando ,
First, I would like to recommend you check the next documentation about tenant , accounts, etc. : https://learn.microsoft.com/en-us/microsoft-365/enterprise/subscriptions-licenses-accounts-and-tenants-for-microsoft-cloud-offerings?view=o365-worldwide
About your question, usually the organization has a tenant and this tenant have the subscription associated . Therefore if you want to move a subscription A from Tenant A to tenant B you need to have in mind this some steps (https://learn.microsoft.com/en-us/azure/role-based-access-control/transfer-subscription):
- Transfer Billing ownership (https://learn.microsoft.com/en-us/azure/cost-management-billing/manage/subscription-transfer)
- Change the directory (https://learn.microsoft.com/en-us/azure/devtest/offer/how-to-change-directory-tenants-visual-studio-azure)
Keep in consideration transfer role assigments and the impact for users and service principal.(https://learn.microsoft.com/en-us/azure/role-based-access-control/transfer-subscription)
I hope this brief information can help you.
Cheers,
Luis
