I thought I would document migration issues I've had going from iPhone 4 (originally 5.1.1) to iPhone 6 (8.0.0) for anyone who may be wondering what items they may lose. My iPhone 4 was originally restored from an iPhone 2G. These issues have been present after doing the following:
I currently have no solution to any of these. I have another 20 days before I have to trade my iPhone 4 in to ATT so hopefully someone will have better luck than me in finding a fix.
- iPhone 4 (5.1.1) iTunes backup -> iPhone 6 (8.0.0)
- iPhone 4 (7.1.2) iTunes backup -> iPhone 6 (8.0.0)
- iPhone 4 (7.1.2) iCloud backup -> iPhone 6 (8.0.0)
- iPhone 6 (8.0.0 iTunes backup -> iPhone 6 (8.0.0)
- Voicemail over 30 days did not transfer over. See https://forums.macrumors.com/threads/1785265/ for more information.
- Recent/Missed calls showing as "No Caller ID". This includes numbers that were just phone numbers and not associated to a contact.
- Lifetime call time not correct.
