When upgrading, if you have customized the JDK installation used by EAServer, you may need to apply the customizations again. Your options are:
If the existing JDK is at the correct patch level, choose the Custom option when installing. The installer prompts for the location of your existing JDK and configures EAServer to use it. See “JDK versions” for more information.
If the existing JDK is not at the correct patch level, install a new JDK version from the CD and reapply your customizations.
