I am trying to prepare for the switch in the SSL certificate vendors.
For the the SSL validation, Our Tomcat web application uses a JKS file created from a DigiCert certificate ( *.cer files). Our company is now switching to VeriSign next week. Since they have already provided the new *.cer files, can I simply add the new cert ( using keytool) to the existing JKS so that it works for both certificates. I am trying to avoid any downtime during the switch and prepare the server beforehand?
Any helps will be much appreciated.
