If you are cloning then no you should not have to re-install.

According to the manual it does delete both the zip file and the KMH, but Roy may be right that it only deletes the KMH file. I don't have any files that use the KMH, so don't know for sure. You may want to look through your ZIP file folder and see if there are any that don't have KMH files. If so don't copy those over and you should have your duplicates removed still.
