Reissue can be used to get the new certificate file with new pair of keys.

The reasons for certificate reissue:

• issuing the certificate for the next period within the product’s validity period, when the issued certificate is shorter than product validity date of the ordered product,
• private key is lost or it needs to be changed,
• other key algorithm or length is needed,
• error appears during installation or certificate and private key mismatch,
• web server/hosting provider was changed.

After the new certificate is issued, revoke previous certificate if it will not be used anymore.

If verification of the subscriber and organization identity expired, it is required to verify it again
(update data prevalidation). If verification of the control over the domain or e-mail address has expired,
it is also required to verify it again.
