I can tell you for certain that an upgrade should not affect your certificate--mine continued unchanged over several upgrades. I have seen a couple threads where people did break certificates on upgrade, but I'm not sure how they managed this as mine have worked without a hitch.

As to installing on a bigger hard drive, I don't know for certain because you would be (presumably) doing a clean install rather than an overlay-upgrade. At the worst, you might have to re-generate the CSR and use it to re-generate your certificate. Since I have not tried this I can't speak from experience whether this will be necessary or not.
