I'm giving my old phone away and all my contacts are still synced on both phones. If I delete one contact off one phone, the other phone deletes it too. I already logged out of my apple id on my old phone and turned off the contacts switch in settings under iCloud. How do I make the two phones separate, so I can wipe and reset my old phone without it affecting my new phone?
iPhone 11

The second new iPhone will be disconnected and will be still signed in with the Apple ID and and password .
