how to transfer contact fron one iphone to another iphone with different Apple ID

iCloud uses Apple ID credentials

Unlike some Android devices, contacts are neither stored locally on an iPhone nor in SIM. They are synced to an email account that you had Google, iCloud, AOL, Exchange, Outlook, Yahoo or any Other

If your contacts are on iCloud using another Apple ID then you need to add that iCloud email in the iOS App which uses another Apple ID.

You can have multiple iCloud emails under the iOS mail app.
