guidelines for importing CIS configuration

Within exported CIS configuration files are UID and GUID entries. Which of these are installation specific? I see that the predefined policies are common across installations, but nothing additional is. If I try to import a config into an existing installation, how can I ensure that UID & GUID aren’t somehow stepping on something.

It seems that configurations for CIS v10.x are more finicky in that regard than previous versions. Certain applications have a great many access name permission attributes and it would be great to be able to cut / paste the information from one CFGX to another.
