I have a question about updating and sub-theming. I currently have Acquia Marina 6.x-2.0 installed and am looking to update to v3. but want to keep the current theme in place until I get v3 completely together with an updated aesthetic for the site, etc. . . I currently don't have Fusion installed and am unsure of how this will impact the update.
How would I go about accomplishing this?
Creating a sub-theme of v2 and updating it to v3?
Will renaming v3 and uploading it to the server work on it's own without an updated version of the base theme?
