Configuring SSL certificates for two servers


My org has two domains

I have two servers that will work behind a load balancer that will be for our second domain instance. The public cert is - I have the public entrust certificate and I've gone through the steps using Keytool on my primary server from: Enabling SSL on Tomcat. I imported the root, intermediate, and server certificate

I was not the admin that configured the first instance - however using keytool -list, it appears the secondary in that case does have the certs in the keystore

I have not yet uploaded the .jks file because I have a second server.

Do I need to run through the same steps on the secondary Windows server? If so - if I were to upload the .jks file - wouldn't it just overwrite what I uploaded on the primary server --- since it's using the same database?
