Copying from one EWM project area to another

Is there any utility (similar to ETMCopyUtility for ETM) to copy the data from one EWM project area to another? We want to copy work items (along with planned for iterations). After searching in jazz.net forum, I understand this can be asked only through services engagement. Can someone please let me know the steps that will be used by services team? Or just the approach that can be used.
