Website domain name transfer, what should I do with the deployed SSL certificate?

Friends who are familiar with SSL certificates know that SSL certificates are a type of digital certificates. They are usually deployed on website servers. They can implement HTTPS encrypted access and play the role of authentication and data encryption. In addition, most of the SSL certificates are applied for by the domain name. If the website domain name is transferred, what should I do with the SSL certificate deployed on the website before? Will it be transferred as well?

Before we know whether the transfer of the domain name will affect the transfer of the SSL certificate, we need to know whether the SSL certificate can be transferred?

The answer is yes. In general, most people's practice is to directly resolve the domain name to the new server IP first, wait for it to take effect, and directly apply for a new SSL certificate, and then import the database and file migration. Relatively speaking, the latter SSL certificate migration is more troublesome, or it is easier to reconfigure it directly.

When there is a domain name transfer, and the website deploys a single domain name SSL certificate, the certificate will also be transferred with the domain name, because a single domain name SSL certificate can only protect one domain name website, as long as the domain name is not cancelled, then the certificate is valid within the validity period It will also take effect with the domain name to protect the security of the website;

If you deploy a multi-domain or wildcard SSL certificate, if one of the domain names is transferred, the following SSL certificate can also be transferred. Other domain name websites are not affected and can continue to enjoy the protection of the SSL certificate. After all, multiple domain names Or wildcard SSL certificates can be used on multiple servers at the same time.

Generally, the validity period of the SSL certificate is one year. In order to avoid the trouble of transferring the SSL certificate, you can choose to transfer the domain name when the SSL certificate is about to expire. At this time, transfer the domain name and purchase a new SSL certificate in advance to deploy, which not only saves the trouble of transferring the SSL certificate, but also does not affect the normal operation of the website.
