Sorry bout the slightly dumb question but... I have Wild Hunt installed, together with all of the patches and expensions...

If I want to install the GOTY edition, how should I do that... I do not want to have the game installed twice... and there doesn't seem to be an option to just "patch" to GOTY edition... should I use the "import folder" option?

Sorry if this has been already asked... I'm just a bit confused...
