Apple says "Your iOS Distribution Certificate expiring" what i need to do
I got this mail from Apple.
Your iOS Distribution Certificate will no longer be valid in 30 days. To generate a new certificate, sign in and visit Certificates, Identifiers & Profiles.
I get some information from StackOverFlow but I want to know what I need to do if I modify my existing app. Will I able to update in future the same app with new certificate and new profile. Is that I need to revoke and generate the new certificate. Thanks for your help and comments.

It is just a reminder of the certificate that is going to be expired very soon in future.

Yes, You can always able to create new certificates (Some has limitation to create) and use these certificate to generate new mobile provisioning profile or regenerate mobile provisioning profile using the new certificates.
Using old certificate (Expired) you can not able to run build on device and not able to publish app on App Store.
The new certificate will not affect on your app. In simple words, certificates are being used to run app on device, publish app on App Store, push notification, etc.
