    Hello.

    I don't know if we have IT people on NamePros familiar with SSL certificates, but I have a question and would really appreciate to get some help.

    All companies and domains mentioned are purely for example purpose.

    Lets say company OKBoss Inc. currently own the domain name www.okboss.com, registered at Enom. They configured the DNS to point to their hosting plan on HostRat and they have their valid SSL certificate on HostRat aswell for their domain www.okboss.com

    Now, I made a new website for them. Its ready to be used but it is installed at a different hosting company. Let's say its at HostSquirrel.

    At Enom, when they'll be ready, I will only change the DNS to point to the new server IP at HostSquirrel and it will work. That part I understand and I am familiar with.

    My question is regarding the SSL certificate. Currently a PFX file.

    Can I take the same PFX file that I use at HostRat and install it at HostSquirrel and it will work as soon as the DNS is changed, the new website will be working HTTPS.

    Or do I need to have a new certificate issued for the new server? If I have a new certificate issued for the domain, will the one that currently active stop working immediately?

    My fear is to have a downtime because of the certificate.

    I want the current certificate to remain active for as long as the DNS is changed. And I need to have a certificate installed on the new server in advance to make sure the website HTTPS will work as soon as DNS is changed.

    I don't know if I am clear. Anyone can enlighten me on this topic?

    Thanks for your help.
    Dom.

    SSL is a service not a certificate or a file.

    What it does is to scramble the data transfer back and forth between two computers - when http becomes httpS

    You need a new SSL for the new server.
    SSL certificates match the CSR (Certificate signing request) from the server and some SSL insists even on a dedicated IP.

    You can add the domain to the new host before changing the dns and generate a CSR and get a new SSL certificate. Then transfer all files/databases and it will be a seamless transfer.

    Thanks for the help tldboss.

    Two simple steps :

    I exported the certificate from current server to PFX file.
    I imported the PFX file to new server.

    Bingo !! Works like a charm.
