Photos and presets only transfer automatically from one device to another for users with paid Lightroom subscriptions. Are you a paid Lightroom subscriber?
If you are a free user, and your devices are iOS devices, the easiest way to migrate your previous Lightroom files and presets to the new device is to do a full iTunes/iCloud backup of the old device and restore onto the new device.
Hi Kevin. Do you have still your previous iphone with Lr installed available. if so you could create an iOS backup and setup your new phone from this backup. With that you would have all data preserved. hope this helps, Guido/ Lr Mobile QE
