Do I need to use a new unique value when I reprocess a certificate or order a certificate for a prevalidated domain name?
重新处理证书或为预先验证的域名订购证书时是否需要使用新的唯一值？
The unique value is required at the time that domain control is validated. Therefore, if you add a new domain name when reprocessing a multi-domain certificate and wish to use the DNS CNAME lookup or HTTP/HTTPS file lookup validation method, you will need to create a new CNAME or validation file, with a new unique value. If you have prevalidated a domain name via the CNAME or File Lookup methods, a new DNS record or file with a new unique value is not required when ordering a certificate for it.
