In method public static String toLowerHyphen(String inStr) of
sli/provider/src/main/java/org/onap/ccsdk/sli/core/sli/provider/MdsalHelper.java

Using the following statements to do the format conversion:

String regex = "(([a-z0-9])([A-Z]))";
String replacement = "$2-$3";
String retval = str.replaceAll(regex, replacement).toLowerCase();

It works well for the case such as UpgradePreCheck.
But when there are two continuous capital letters, such as downloadNESw, it will convert to download-nesw, and the correct format is download-n-e-sw.
