Hi,
You can create a CAR package using ColdFusion admin. This option is available under Server Settings>Archives and Deployment which you can further deploy in ColdFusion 10.
As it is not certified to use CF 6 in Windows 2008, you cannot install it. But it won't stop you to install it however it is not recommended.
ColdFusion 10 is certified and tested with Windows 2008 and Windows 2012. So you can go for CF 10.

Hope this helps.
Thanks,
