[SOLVED] Upgrade from 3.2 to 3.6.1

Dear members and developers,

I apologize if i've chosen the wrong section to post...I'm having a trouble in managing the upgrade from the version 3.2 of the theme to 3.6.1.

So the website with the 3.2 is this way:
http://grab.by/8DC7

Instead with the 3.6.1:
http://grab.by/8DC9

I don't understand how to get the 3.6.1 looking like the 3.2...

where do I have to start to recover the old style/layout/graphics ?

Thank you very much for any help!
