Contacts
I removed several defunct email accounts...b/c contacts were associated with those accounts they too were deleted. How do I recover the contact information?
The only way to get the Contacts back is to add the accounts again.
Google to iCloud
Try to export the contacts from google mail on a web browser. During Export select export as vCard and then
log in to https://www.icloud.com using your Apple ID credentials Tap Contacts app > Settings > Import vCard.
iCloud to Yahoo.
Log in to https://www.icloud.com using your Apple ID credentials Tap Contacts app > Settings > Export vCard.
iCloud will import or export only vCards. You need a third-party app to convert vCard file to CSV as Yahoo will only import using CSV file --> Import, export or print contacts in Yahoo Mail - SLN28070
