Integration Key working w/ SOAP requests

Hello All,

When swapping out the old apiKey with the new Integration key I am able to pull data with my legacy SOAP requests. See the below snippet of XML.

Will this continue to work after the OAuth switch?

https://secure.echosign.com/services/EchoSignDocumentService16

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">     <soap:Body>         <getDocuments xmlns="http://api.echosign">             <apiKey>3AAA9999999999999999999999**Integration*key**9999999999999999999999</apiKey>             <documentKey>12345</documentKey>             <ns5:options xmlns:ns5="http://api.echosign" xmlns:ns4="http://dto11.api.echosign" xmlns:ns3="http://dto13.api.echosign" xmlns:ns2="http://dto9.api.echosign" xmlns="http://dto14.api.echosign" />         </getDocuments>     </soap:Body> </soap:Envelope>

Thanks
