Steam will minimize and start downloading. It will say "Downloading..." but progress may not show immediately. Wait until the console says "Depot downloaded." (This can take 10–30 minutes depending on your internet speed).

Once finished, Steam will tell you where the folder is. Usually: C:\Program Files (x86)\Steam\steamapps\content\app_489830\depot_489831.

Open that folder. You will see the old game files.

Copy ALL files from that folder.

Go to your actual Skyrim installation folder (usually C:\Program Files (x86)\Steam\steamapps\common\Skyrim Special Edition).

Paste the files and select "Replace the files in the destination."
