Recover contacts without sync icloud
Hello. I have an iPhone 7 with 1.800 contacts, but they are linked to a business account. This account don't exist anymore, and I can't bring them to my new iPhone 15. I'm searching the fast way to move them from my old iPhone to the new one, without share them one-o-one.
For example, is it possibile to move them from the business account to iCloud using only iPhone?
Or, maybe, I can use Finder/iTunes, but the info tab say that over-the-air syn is active on iPhone, and I can't access to them: how can i disable it and access on contact from Finder?
Thank you in advance
