# Azure Storage Queues Transport Upgrade Version 7 to 8



## Sanitization

In previous versions, the transport was responsible for sanitization of the queue names. That included:

 * Replacing invalid characters
 * Converting name to lowercase
 * Shortening queue names exceeding the maximum allowed queue name length, using [SHA1](https://msdn.microsoft.com/en-us/library/system.security.cryptography.sha1.aspx) or [MD5](https://msdn.microsoft.com/en-us/library/system.security.cryptography.md5.aspx)

In Versions 8 and above, the transport is no longer performing sanitization by default. Instead, sanitization logic must be [registered](/transports/azure-storage-queues/sanitization.md).

```csharp
// For Azure Storage Queues Transport version 11.x
var transport = new AzureStorageQueueTransport("connection string")
{
    QueueNameSanitizer = queueName => queueName.Replace('.', '-')
};

endpointConfiguration.UseTransport(transport);

// For Azure Storage Queues Transport version 10.x
var transport = endpointConfiguration.UseTransport<AzureStorageQueueTransport>();
transport.SanitizeQueueNamesWith(queueName => queueName.Replace('.', '-'));

// For Azure Storage Queues Transport version 9.x
var transport = endpointConfiguration.UseTransport<AzureStorageQueueTransport>();
transport.SanitizeQueueNamesWith(queueName => queueName.Replace('.', '-'));

// For Azure Storage Queues Transport version 8.x
var transport = endpointConfiguration.UseTransport<AzureStorageQueueTransport>();
transport.SanitizeQueueNamesWith(queueName => queueName.Replace('.', '-'));
```


## Serialization is mandatory

In Versions 7 and below, the transport was setting the default serialization. In Versions 8 and above, the transport no longer sets the default serialization. Instead, it must be configured. 

For backwards compatibility with the previous default serialization, `NServiceBus.Newtonsoft.Json` serializer must be used.

```csharp
// For Azure Storage Queues Transport version 11.x
endpointConfiguration.UseSerialization<NewtonsoftJsonSerializer>();

// For Azure Storage Queues Transport version 10.x
endpointConfiguration.UseSerialization<NewtonsoftJsonSerializer>();

// For Azure Storage Queues Transport version 9.x
endpointConfiguration.UseSerialization<NewtonsoftJsonSerializer>();

// For Azure Storage Queues Transport version 8.x
endpointConfiguration.UseSerialization<NewtonsoftJsonSerializer>();
```
