How to change ssl certificate to Vestacp?

Question

Digital certificates

I apologize in advance for a possibly stupid question, but I had a bad experience changing the certificate, so I'm asking for help.
I have a let'sencrypt certificate on the domain on my virtual server with vestacp. Another certificate was bought and now it is not clear how to change it. Do I just upload the new keys in the vesta panel instead of the old ones, or do I need to remove the old certificate somehow first?

Answer 1

Is it just to upload new keys in the vesta panel instead of the old ones or do I need to remove the old certificate somehow first?

Why not? Check it out on a test site
