Upgrade to final release of Yosemite from gold master?

I'm using developer preview of Yosemite for a while, now that Yosemite is released I want to have it installed on top of my Yosemite partition.

Clicking on "Download" in App Store Yosemite page, I see that I am prompted with an error note, saying :

Os X v10.10 is already installed on this computer. Use the Updates page to install the 10.10 update or if you would like to download the full OS X installer click Continue.

There's only two buttons; "Learn More" and "OK". OK does nothing, and there's no relevant update note regarding switching to full version of Yosemite so it's not rleevant neither.

How can I download full, final OS X Yosemite 10.10 release and install it on top of preview partition?

Solution 1:

All the coverage I've seen says to run what you have and 10.10.1 will convert all pre-release versions of OS X - including the latest GM candidates to the full production version.

You are free of course to go through the work to download the free version of the installer and see if it runs on your specific version of OS X but without knowing your exact build and source of the pre-release software, it's hard to be more specific.
