ios - Enterprise Deployment certificat and profiles -

I am currently using the iOS Developer Enterprise program for enterprise deployment. I want to know what will happen when certificates and / or provisioning profiles end. So far, I made a bunch of provincial profiles till I can do it till the date of expiry. I want to know if I can safely remove old provisioning profiles that might be linked to an app or the application stopped working. Is it possible in some way that a user who is already downloading an app will not be able to open it or a new user will not be able to download it.

Thanks

<> The only requirement for an app running on iOS device is that at least one valid (non-expired) provision profile on the device Has been signed with a valid certificate (without expiration / deletion) in which there is a bundle id that matches the app's bundle ID which you are trying to run

then We say that I have 2 provisioning profiles That is designed for the app in the year. The app's bundle id "com.example.testapp" was created with an API ID "com.example.testapp" from the pricing profile and it expires in 1 month. Another provisional profile was created with a wildcard app ID "com.example. *" And it expires in 3 months. Being able to run on devices, you can safely remove the provisioning profile at any time and create a new one, without affecting the currently deployed apps. Once they touch the date of expiry, they will stop working.

Continuing this example, suppose you have installed another app on the same device with the bundle ID of "com.example.testapp2" and basically with a provision profile Which was specifically installed on the App ID "Com.example.testapp2" and the provision profile tomorrow will expire. After tomorrow, the app will still work because the "com.example.testapp2" provision profile has expired, yet another prov matches a profile on the device with a wildcard app ID, and it Profile is not yet finished.

On any other device whose only test is App 2, and the Wild Card Provisioning Profile has never been installed, the app will stop working, either manually by emailing the device user Can install), or bundle a new app (or a single app) with a new provision profile.

Such a long story short, removal provision profiles are generally safe, but unless you are ready to re-pack all your internal apps, do not cancel the certificate.
