How to upgrade OS and preserve Elements 13?

I need to upgrade my OS from Win 8.1 to Win 10 soon (due to MS ending support for 8.1) and I need to know how to migrate my Elements 13 program to Win 10 and keep all data files and settings intact and not have to re-purchase the license or install a newer version. Note - data files are on a separate HDD (F:) but have noticed some similar files on C: that I'm afraid might be linked to the files on F: and don't want to risk losing either set. Would appreciate any help. Thanks.
