How to support both DataContractSerializer and XMLSerializer for the same contract on the same host?

In our production environment, our WCF services are serialized using XMLSerializer. To do this, our service interfaces have the [XMLSerializerFormat] attribute. Now we need to switch to the DataContractSerializer, but we must remain compatible with our existing customers. Therefore, we must expose each service using serializers.

We have one limitation: we do not want to redefine each contract interface twice, we have 50 contract service interfaces, and we do not want to have

IIncidentServiceXml 
IIncidentServiceDCS
IEmployeeServiceXml 
IEmployeeServiceDCS
IContractServiceXml 
IContractServiceDCS

How can we do this?

Additional Information

This is a description of what we have tried so far, but I am ready to try completely different approaches:

XmlSerializer :

<Customer xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

DataContractSerializer :

<Customer xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/ConsoleApplication1">

How about two services running the same contract?

how

class DcsService : Service
{}

[XmlSerializerFormat] 
class XmlService : Service
{}

class Service : IServiceContract
{}

Never worked with XmlSerializer, but we used this construct for other purposes.
