I just tried to do this and I am ticketed in an appropriate fare class (Q) with a ticket number beginning with 988..
Called reservations and they told me:
1. The ticket must have been purchased through the website.
2. You must be an Asiana Club member.
I purchased my ticket at an Asiana ticket office and I am not an Asiana Club member. The agent told me I was out of luck.
Just for fun, I created an Asiana log in, entered my reservation information after loggin in and confirmed what the reservation agent told me: which clicking the upgrade option, the resulting page told me my ticket is not eligible.
