what I know is, if they issue you the Visa on the new passport. All you have to do is to go there and ask for transferring the Visa to the new one and should not be a problem. Would only cancel the old one and issue you a new one. I traveled with the old passport before which has the visa and I was showing them both. The new one for validity purpose and the old one for the visa validity purpose. There were no problems at all, maybe you should cut the strings of doubt by visitng the Immigration yourself or ask your company to do that to clear that matter to you.
