Upgrade 2.0 to 2.2

Hi,

Just would like to know the correct procedure to upgrade my NopCommerce 2.0 website that has customised themes and views to 2.2.

Should I just do a fresh checkout of the 2.2 release and manually merge changes with my customised 2.0 version. Or are there scripts that need to be run on the database?

Regards,
Seth

Ok done a checkout of 2.2 and can see the upgrade scripts from 2.0->2.1->2.2.

Just wondering about the procedures so I don't lose my customised views and themes.
