When I copied over, and tried to start WebLogic, got an exception:
weblogic.management.ManagementRuntimeException: com.rsa.jsafe.JSAFE_PaddingException: Could not perform unpadding: invalid pad byte.
It's really not telling what you'll have to do. After some research, I figured out I need to re-encrypt the password. Here's the utility to use:
java -cp <weblogic_home>\server\lib\weblogic.jar -Dweblogic.RootDirectory=<your_domain_dir> weblogic.security.Encrypt <password>
Pasted the result to replace old password, it worked fine.
