WARNING These steps are probably out dated and will not work.

To re-sign an iOS app with another developer account, ensure that the following are in place first.

1. Distribution certificate of the other developer account
2. A provisioning profile from the other developer account

Note that the Apple requires bundle IDs to be globally unique, even across accounts. So a bundle ID i.e. CFBundleIdentifier from one account can't be used in a different account, even though the team id/prefix would be different.

Ensure that the new distribution certificate is in your keychain and the new provisioning profile on your disk.
