You have an Azure subscription that contains the storage accounts shown in the following table.

All storage accounts contain blobs only. You need to implement several lifecycle management rules for all storage accounts.

C . Move 5 TB of blob data from contosostorage1 to contosostorage2.
D . Recreate contosostorage5 as a General Purpose V2 account.

Microsoft recommends that you use a general-purpose v2 storage account for most scenarios. You can easily upgrade a general-purpose v1 or an Azure Blob storage account to a general-purpose v2 account with no downtime and without the need to copy data.
