You will have to manually carry over the customizations to the sp3 database for the objects that are versioned with the sp3. Also you will have to import the difference in roles and permissions. There is no datakonversion involved.
I would import your customized sp2 and a std sp2 into ndt and copy/paste the differences over into the sp3 using the compare two versions feature, yes.
