I currently have mine and my partner's phones using the same Apple ID. As we are about to upgrade my partner's phone, we would like to set up her new phone with an individual ID. Is this possible without losing the data stored on her current phone? (Switch is 11 pro-max to 14 pro-max)
iPhone 11 Pro Max, iOS 16

When changing to the new ID, make sure you turn off Find My Phone before signing out of the old ID. Once signed out and Find My Phone is off, then sign in with the new ID, then turn Find My Phone back on. There may be some data loss, but you can minimize it. If syncing photos with iCloud, ensure Optimization is turned off in Settings/Your Name/iCloud/Photos and/or in Photos/Preferences/iCloud. Then make sure full resolution photos are on the device/computer. When signing out of iCloud, if asked whether you want to retain data, choose yes. Messages conversations will be lost if they are addressed to the ID. See the article below for other places that the old ID should be removed. See Winston Churchill's response in the below discussion. If possible, also set up Family Sharing between the IDs to keep access to your apps/purchases.
