Maybe this is the wrong section for, but I consider it technical help

I'm thinking of eventually getting the SoW 150th Anniversary Edition, instead of buying all the remaining expansions I don't have (for some reason it's cheaper

How do I go about "migrating" over my progress from SoW Gettysburg to the new 150th Anniversary installation, that is my saves, scores and scenario status and carryovers? Just copy over the "Work" folder to the new installation?
Thanks!
