Copy a Java keystore on one machine to another?

I have a keystore on one machine (at /root/.keystore) and I want to move it to another machine at the same location. Currently, the second machine doesn't have a keystore at /root/.keystore, is there a way I can export then create/import? Or do I need to create an empty one first?

Keystores are simply files in a format used by java for storing keys and certificates. They do not contain any information which ties them to a particular system. They can be freely copied between systems and directories as required.

They may be password protected, in which case you may need to arrange to have the password available to the software using it. There is a keytool program which can by used to read and/or update the keystore. It is often possible to read keystores without a password.

Keystore may contain keys tied to a system's domain name. These keys are not as useful on other system.
