Hello @SwojasLab
Thank you for reaching out to the Microsoft Q&A platform. I am happy to answer your question.
To migrate a Pay-As-You-Go (PAYG) subscription to a Cloud Solution Provider (CSP) subscription model, you need to follow these steps:
- Ensure that the source and target subscriptions are in the same Azure Active Directory (Azure AD) tenant. You can't change the Azure AD tenant for an Azure CSP subscription<sup>.</sup>
Instead, you must add or associate the source subscription to the CSP Azure AD tenant
The user account that you use to do the transfer must have Azure RBAC owner access on both subscriptions. - Validate that all Azure resources can move from the source subscription to the destination subscription. Some Azure resources can't move between subscriptions.<sup>[0]</sup> To view the complete list of Azure resources that can move, see Move operation support for resources.
- Verify that all source subscription services use the Azure Resource Manager model. Then, transfer resources from source subscription to destination subscription using Azure Resource Move.
Here is the official document from microsoft on transfers of subscriptions to CSP that provides brief details https://learn.microsoft.com/en-us/azure/cost-management-billing/manage/transfer-subscriptions-subscribers-csp#other-subscription-transfers-to-a-csp-partner
Hope this helps!
