I upgraded from Windows 7 to the 10074 Preview via the Insiders page, then upgraded to each new build after that to 10240 via Windows update. I lost track of how many upgrades I did, 6 or 7 maybe? A few glitches along the way, nothing big though. Tiles with no icons in them and one or two with weird names. Fixed easily though. I had issues with early builds before 10074 though, and ended up doing a clean install to fix things.
