@Saha - Thanks for the question and using MS Q&A platform.
The following visual illustrates the guidelines to choose the various Azure data transfer tools depending upon the network bandwidth available for transfer, data size intended for transfer, and frequency of the transfer.
To copy 8TB of data from one Azure subscription to another, there are several options available.
One option is to use Azure Data Box. Azure Data Box is a physical device that you can use to transfer large amounts of data to Azure. You can copy your data to the Data Box, and then ship the device to an Azure data center for loading. This option is ideal if you have limited network bandwidth or if you need to transfer a large amount of data quickly.
Another option is to use Azure ExpressRoute. Azure ExpressRoute is a service that provides a dedicated, private connection between your on-premises infrastructure and Azure datacenters. You can use ExpressRoute to transfer data between Azure subscriptions. This option is ideal if you have a high bandwidth connection between your on-premises infrastructure and Azure.
If you are not able to use AzCopy, you can also use Azure Data Factory to copy your data. Azure Data Factory is a cloud-based data integration service that allows you to create data-driven workflows to move data between on-premises and cloud data stores. You can use Data Factory to copy your data from one Azure subscription to another.
In terms of cost, the best option depends on your specific requirements. Azure Data Box has a one-time fee for the device rental, and you will also need to pay for shipping costs. Azure ExpressRoute has a monthly fee based on the amount of data transferred. Azure Data Factory has a pay-as-you-go pricing model based on the number of data integration activities you perform.
