If you have your own SSL certificate and want to import it to us, here is the steps you can do:
1, export the certificate with .pfx file from old hosting providers.
2, go to member account >> Add-On Products >> Purchase Add-Ons to purchase a static ip for the SSL first.
3, Go to hosting control panel >> SSL manager>> my SSL list to click the “Import the existing ssl certificate”. Choose the .pfx cert type, put in the correct import password (the password is generated from old hosting providers while exporting the cert), then click the browse icon to import the .pfx file from local to our servers.
