Renewing Development & Distribution Certificates - Should I use the same CSR for both?

Question

I need to renew my Development & Distribution Certificates. It's expiring soon and I'm a bit worried doing so before being 100% sure I'm doing the right thing. (there are 20 apps on the app store attached to those Certificates ) Any way, I've read a few guides online and couldn't find an answer for that, after I request a new CSR from my keychain, should I use the same certSigningRequest file bor both Development & Distribution or should I create a new one before each one?

If I didn't save the CSR from last year, will I need to upload new pems file to gain back push notifications on my apps?

Answer 1

Yes you can. There's nothing wrong with that, I do it all the time. In fact, keep your CSR so you can use it in the future and save yourself some effort.
