Can I update existing apps in the app store if I have rejected my distribution certificate because I lost my private key?

I have done A LOT of looking around on the internet and just cannot find the answer to this question. I lost my private key, and so I have rejected and re-assigned new certificate/key combo, but am having issues submitting app updates to apps signed with the old key with my new key.

Is it possible to update an existing app with a newly replaced private k开发者_开发知识库ey that is different than the one it was originally signed with?

Yes, you should be able to submit app updates with a different distribution certificate. I've done it on multiple occasions. What specific issues are you having?
