Certificate transfer between 2 zimbra mail servers

Hello everyone, as communicated by the other thread, I have dismissed the old e-mail server where among other things there were also the new renewed certificates (I still have the possibility to enter the old server if necessary).
On the new server, what procedure do I have to carry out to get the certificate again without messing around? Thanks in advance to everyone

You should probably follow the Zimbra instructions (as if doing this from new installation).

ok I proceed, but the request, since it will always be for the same domain, won't it go into conflict / error?

There are rate limits.
See: Rate Limits - Let's Encrypt (letsencrypt.org)
And you can check how many certs have already been issued at: https://crt.sh/

Ok perfect, thank"s
