I just upgraded to an iPhone 6 from my well-used but faithful 4S. I'd put off upgrading the operating system on my 4s, but as of now it's running 8.3.1. I then did a fresh back-up of my 4s. I also upgraded my 6 to 8.3.1 immediately on receiving it. I backed up my 4s to iTunes(188.8.131.52 on OS X 10.9.5), and then attempted to restore the backup to the 6. When I try to get do this the restore seems to proceed normally for a few minutes, but I then get the below message I get the below message in iTunes I've been able to get my apps, contacts, and photos transferred over, but at least in the past when I got a new iPhone(about 3 years ago) I was able to transfer all my preferences and everything else over to the new phone. At this point, I'd like to-if nothing else-get my text messages/iMessages transferred over. Any thoughts on what's going on-or at least if what I'm doing is not possible how I can transfer my messages over to the new phone. It would also be great to transfer my email accounts without having to manually re-enter them. Thanks in advance for any help.
