How to upgrade Individual Developer Account to a Company Account?

Solution 1:

The best manner to accomplish this is to contact Apple Developer Program Support directly.

You can find their phone number and initiate a support ticket from this web page:

• https://developer.apple.com/contact/

I have found them to be expert at getting you the information you need to effect a smooth and orderly transition and help you from registering incorrectly or having any assets trapped in limbo if you make the transition incorrectly.

Solution 2:

Apple now provides an "Individual to Organization Membership Update" form to convert a personal account to a business account.
