Added some additional context and help to the "Attention points" sub-header with some useful commands for validation of the existing certificate.

You can validate your existing and new certificates with `openssl x509 -text -noout -in /etc/xensource/xapi-ssl.pem | grep Public-Key`. Running this will either output `1024` which has been depreciated or `2048` which is supported for XCP-ng 8.3.X.

In some rare scenario's you may have very a very old version of XCP-ng still installed in a backup file on your system, please open a ticket with support if this is the case. Alternative, you may need to perform a fresh installation of XCP-ng erasing all configuration on a given host.

I don't understand why the backup partition would cause any issue. Can you explain?

If you never installed custom host certificates, then you are likely using the default self-signed certificate XCP-ng generates the first time it is installed. In this case, you can generate a new one, from XCP-ng 8.2.1, with the command `xe host-emergency-reset-server-certificate` on the host.
