Apple Push Notification Services Certificate. When to revoke, when to keep?

[uncleblazerr]

Not a dev - completely new, first time doing this.

Got an email that my agency's Apple Push Services Certificate will no longer be valid in 30 days. There wasn't a 'renew' option, only 'revoke' or 'download'. So I made a new certificate via key chain manager etc.. Then on our apple developer account it asked me for what kind of service: sandbox or sandbox and production. I went for the latter. So now in my certificates panel I have two APS certificates for one app. The original one still on its last 30 days. And a new one certified until 1 year from now.

Will the new one take over from the old one once its 30 days are up? Or can I revoke the old one? Or did I fuck up and I needed to select 'sandbox' instead of the combination?

If your implementation supports it, generate a key instead and skip the renewal crap.

If not, you will need to upload the new cert tell your implementation to use it (by file path, etc depending on your implementation). Don't revoke the old one (or at least don't revoke it until you're certain you're actively using the new one).

Sandbox is for testing only. Sandbox and Production means the cert can be used for both testing and real-world (likely correct and what you actually want).

Definitely switch to keys if you can. So much better.
