User level: Level 1 (23 points)Using Quick Start while old iPhone is still optimizing
I just upgraded my 17 Pro yesterday afternoon from iOS 26.6.7 to 27, and it's still optimizing search and Siri. The largest content categories on the phone are:
Songs 8,000
Videos 700
Photos 13,000
Notes 3 GB
Messages 1 GB
My question: Would there be any issues if I go ahead and use Quick Start to set up a new 18 Pro using the old phone as the source, even though the indexing on the old one is still running?
Thanks.

It shouldn’t be a problem, but if it is just force-restart the new iPhone and wait for the indexing to finish.
It’s worth knowing that the indexing pauses when the phone is in use. If you don’t do so already, plug the iPhone in overnight with a Wi-Fi connection.
