Need to duplicate a queue

Hi All,

We have to recreate our legacy monitoring component for the provisionning system.
The provisionning system contain three components each of them will send informations(messages) about any flow received to a queue on the borker webmethods 9.6 and so the monitoring component read messages by JMS from this queue.

We need to create a new monitoring component who receive the messages from the provisionning system by JMS.

Problematic : On the production environnment we need to coexist the two monitoring components (legacy and new) during a period of three days to ensure that the new component works well, so as we work with a queue mode the first component that arrives on the message will take it and it will be removed from the queue.
Are there webmethods solutions without modifying the current components (provisionning or legacy monitoring)? Any suggestions?
