Reinstalling vps with certificate limit reached

[oliver_33]

I am trying to understand how a vps works, I have already installed and reinstalled different operating systems many times and sometimes already with the certificate installed.
The problem is that every time I reinstall, I lose the certificate.
Is it possible to use an existing certificate after reinstallation?

My domain is: bubcasa.pt

The operating system my web server runs on is (include version): Centos 7 + vestacp

I can login to a root shell on my machine (yes or no, or I don't know): yes, but i have no knowledge.

Thanks

Yes, it is. You need the certificate and the corresponding private key.

This is why there's a staging environment. Learn it. Use it. Stop doing your testing against the production environment.

This was mentioned to you on your other topic:

If you are gong to be testing, and retesting, you should probably be using the staging environment.
