Forums / Cotonti / Support / Trying to update from Genoa, red fatal errors big time.

Thank you for the advice, 

one thing I just realized is that according to the news post on the home page, the latest version (that i have here trying to update with) is 9.15 and it no longer includes the files needed to upgrade from genoa and sed sites????

So I've downloaded the "legacy" pack here, do I drop that over the siena file structure THEN proceed to updating?
