-## Copy a blob from another storage account
-
-If the source is a blob in another storage account, the source blob must either be public, or authorized via Azure AD or SAS token. The SAS token needs to include the **Read ('r')** permission. To learn more about SAS tokens, see [Delegate access with shared access signatures](../common/storage-sas-overview.md).
-
-The following example shows a scenario for copying a blob from another storage account. In this example, we create a source blob URI with an appended *service SAS token* by calling [GenerateSasUri](/dotnet/api/azure.storage.blobs.blobcontainerclient.generatesasuri) on the blob client. To use this method, the source blob client needs to be authorized via account key.

-
-If you already have a SAS token, you can construct the URI for the source blob as follows:
-
-```csharp
-// Append the SAS token to the URI - include ? before the SAS token
-var sourceBlobSASURI = new Uri(
-    $"https://{srcAccountName}.blob.core.windows.net/{srcContainerName}/{srcBlobName}?{sasToken}");
-```
-
-You can also [create a user delegation SAS token with .NET](storage-blob-user-delegation-sas-create-dotnet.md). User delegation SAS tokens offer greater security, as they're signed with Azure AD credentials instead of an account key.

 ## Copy a blob from a source outside of Azure
 
 You can perform a copy operation on any source object that can be retrieved via HTTP GET request on a given URL, including accessible objects outside of Azure. The following example shows a scenario for copying a blob from an accessible source object URL.
