I had a valid cert. I changed it: I added a subdomain, and removed an old subdomain. No errors.
But now I have two certs:
example.com-001. And my reverse-proxy/webserver (nginx) still uses the old one.
- Is it safe to delete the old one? (
- Then is is safe to rename the new one from
example.comso my existing renewal scripts don’t break?
Or, is it better to delete all certs, and re-issue from scratch? (I won’t hit the limit for this week.)
