ios开发人员证书私钥

Question

my certificate was about to expire, so i revoked the old one from the ios provisioning portal and created a new one with xcode (everything worked automatically). After that i set the provisioning profiles to the new certificate within the ios provisioning portal and pressed the "renew" button within the organizer.

Now i recognized that if i want to use some old ipa (wich was signed with a different certificate) i cannot install it on the iphone (getting some message like signature is invalid or so). I've read that when you create a new certificate you should use the old private key. Unfortunally i dont know where the old private key is located (since i'm new at this project).

Just for clarification: if i would create the new certificate with the old private key, will the old ipa work or do i still have to create a new one with the new certificate signed.

And will there any complications when i decide to update my app within the apple store?

thx for help,

kuku

No, the certificate will not complicate any updates to AppStore apps, just be sure that the BundleID is the same. ( You can't send in a update if the bundle id is not the same).

I've been updating one app for 4 years now and have even switched machines in those years, I have create many different certificates for the same account and update the apps many times.
