Data transfer costs between 2 subscriptions in 2 diferent tenants

Question

I have 50 TB of data to migrate between 2 storage accounts in 2 different subscriptions located at different tenants, but within the same region.
Is there any way official way of migrating this data without incurring in outbound costs of data leaving Azure?
My plan would be to spin up a VM in the same vnet as the storage to access the files within the subscription and then transfer them to the new storage account.

Does any one have some insight on this specific scenario?

@Jorge Rodrigues Welcome to Microsoft Q&A Forum, Thanks for posting here!!

If the available network bandwidth (1 Gbps - 100 Gbps) is high on the Azure VM, you can use azcopy tools to copy the data across storage accounts within the same region which offers free data egress charges.

AzCopy - Use this command-line tool to easily copy data to and from Azure Blobs, Files, and Table storage with optimal performance. AzCopy supports concurrency and parallelism, and the ability to resume copy operations when interrupted.

There are also other tools such as Azure Storage REST APIs/SDKs, Azure Data Box family for online transfers, Azure Data Factory to move the data across storage accounts

You can also choose other data transfer solution based on network bandwidth availability which are discussed here: https://learn.microsoft.com/en-us/azure/storage/common/storage-choose-data-transfer-solution#selecting-a-data-transfer-solution

Hope this helps!
