Bought the wife a new iPad 7th Gen. I plan on doing the old to new migration via bluetooth rather than iCloud (we share the same Apple ID...since the first iPhone in 2007...don’t judge, we’re old and didn’t know better).. Anyway, the old iPad (ios 12.4.7) has a damaged power port and it’s real touchy to keep it working. I can almost guarantee that somewhere in the migration process it might switch back and forth between battery and connected power. Would this interrupt the migration process and cause potential problems? If so, do you think I could make it through the migration on battery power alone? TIA for your thoughts. You folks are great.
