Thank you for contacting us. One thing to mention, with Wi-Fi syncing, you cannot sync directly from one iPhone to another. You would need to first sync to your PC from your old iPhone, then you would be able to sync your new iPhone to the data in mSecure on your PC.
For now, I'm going to have you go through the Wi-F syncing article to see if that helps you resolve the issue: WiFi Syncing Issues
Did that have any effect on the problem?
