production 0.6.9 => 0.8.1 upgrade and rails 2.1.1 support

[Yeti]

I have a web application with comatose and i would like to upgrade
rails to 2.1.1 and comatose to 0.8.1 the problem is that i have a
large database and i don't want to get a wipe out :)

Is there any problems with this type upgrade ?

Is comtose working nice with rails 2.1.1 ?

Not really. I just tried to install the latest uber-alpha. After
installing all the migrations and stuff, I get this nice exception
when accessing the comatose_admin

NoMethodError in Comatose_admin#index

_page_list_item.html.erb where line #7 raised:

The error occurred while evaluating nil.title
