The Yahoo Search Marketing account transition tool will be ending on Jan 5th, 2011 (this Wednesday). The tool helps Yahoo Search Marketing accounts transition over to the Microsoft adCenter.
For users who are uncertain whether they have an account that is available for such a transition, the indication is fairly clear. Once you log in to your account, you will notice a yellow “Get Started” button in your Yahoo account. This button will give you a simple way to transition your account to the Microsoft adCenter UI, which includes importing campaigns.
