Installing fresh on a new laptop. Do ALL service packs need to be installed?

Quick question: I have a new Win10 laptop and want to install CDX6. I have the installation DVD and all 7 Updates/Service Packs. Must I install all the service packs or are they cumulative (each one contains the updates from the previous ones)? If they are cumulative that would mean I only have to install the last one (time saver!).

Also, what's the best way to migrate all my CDX6 settings, templates, symbols, and UI customizations from my old machine?

Thanks for any info.
