iOS Question Change Cert and Prov files

I have uploaded an app to Apple Store with a new set of distribution Cert and Prov files, which is generated by a new certSigningRequest.csr file.

I find the tutorial about the recommended way to work with multiple keys: https://www.b4x.com/android/forum/th...e-certificates-provision-files.48539/#content

Now, I want to generate a new set of distribution Cert and Prov files based on the same certSigningRequest.csr file of Development.

My question is: Can I use this new set of distribution Cert and Prov files to generate a new version of my app, which has already uploaded to Apple Store before? Or I should keep the old set of Cert and Prov files for this app?

Thanks!
