All your app and service listings must be published under a single salesforce.com organization, known as your master AppExchange Publishing Organization (APO). Think of the APO as the organization where you will do all your AppExchange management. If you have a License Management Organization (LMO), we recommend using the same organization for your LMO and your APO. This consolidation lets you keep track of customers who install your app and the leads your listing generates in one place. The Developer edition organization where you create apps should not be designated as your APO.
You can only change your APO if you don't have any public listings on the AppExchange. Once you've made at least one listing public, you can only designate a different organization as your APO by logging a case with Salesforce Customer Support from your partner portal.
