The whole process will be completely transparent to our shared hosting customers, for customers of VPS or Dedicated servers more steps will be required, in all cases there will be no cost attached to either the certificate or for the work required to install the new certificates.
Each customer will be notified before and after the change of the certificate, your web site visitors will have no issues during the exchange of the certificates and the traffic will not be interrupted at any point.
