Is it possible to move an Azure MCA subscription to a CSP without needing to move all resources from the existing subscription to a new subscription? Bonus question - is there a matrix for subscription migrations by type?
Yes, you can do that by doing a billing change. It's described here. https://docs.microsoft.com/en-us/azure/cost-management-billing/manage/transfer-subscriptions-subscri... Basically, for the matrix, you can do a EA (MCA/SCE) to CSP and from PAYG to EA. You will keep your subscription ID in the process, and with no downtime for the users. The process from EA to CSP has to be initated from your CSP partner. All other migrations are ressource by ressource migrations
