iPhone 11 Pro
Question marked as
When you set up the new iPhone from a backup of the old iPhone, the photos will be included, see: Restore your iPhone, iPad, or iPod touch from a backup - Apple Support
Have you already set up the new iPhone and the photos are missing? If the photos have not been transferred from the old iPhone, when you set it up and you have been using the iCloud Photos, you may need to enable iCloud Photos on the new iPhone as well as described here in the second part of the linked document: Get help with missing photos - Apple Support
