I have an application that was released by an enterprise distribution method. The distribute certificate will expire in one month so I created a new one.
In addition, I renewed the provisioning profile based on a new certificate with the same bundle ID and app ID.
The old provisioning profile will expire in one month as like as the old certificate. My app was signed and installed by this provisioning profile and certificate.
So the question is will my existing application that is being used by our users right now stop working when I renewed the certificate and provisioning profile?
As long as you don't revoke the old certificate you will be fine.
With the enterprise program you can have two valid signing certificates at any point; This allows you to issue a second one before the first expires.
