Hi! I decided that after being on ‘1 min remaining’ for over half an hour it was a glitch. I checked the new phone and everything was fine and stopped the transfer. Nothing happened. I’ve now erased the old phone ready to sell on.I'm having this problem too!
I'm noticing the same transferring from XR to 13 mini. The XR has been on "About 3 minutes" for just about an hour. I'll leave it for a bit more, but I'm sure it's actually finished. The new phone seems fine and it did restart as expected during the migration, so I'm guessing the old XR just lost the plot/didn't get the memo... heh...I let it go for hours, no change - stuck at 1 minute. Since the new phone was functional, I just stopped everything. So far, the new phone works just fine. The old phone has since been wiped. The only setup I had to do was bluetooth devices and ApplePay credit cards.
