Hi, created a website for a client using the Streamline theme. (Heavily customized). Theme 1 year ago was V 2.01. Studiopress now released V 3.01 a couple months ago. Questions :

1) What is the easiest way to uprade ? (take into consideration that the streamline 2.01 child theme was heavily customized). Is it possible to created a child theme of a child theme (so : Genesis(parent) -> Streamline(child) -> Custom theme(child of Streamline)) so any future update will be easier ?

2) Is there a log file with the change made to the theme ? I noticed the old V2 was 960px wide & that the new one is 1140px ? Is that possible ?

The new Pro version of Streamline is a completely different child theme – there is no reason to update unless your client wants a whole new design. Any customizations made to the old version of Streamline would be lost.

Is the current site mobile responsive? I know the theme is, but some people remove the mobile responsive elements. Technically you could change the grid on the old theme to be 1140px wide but you’d have to alter a LOT of CSS, especially to maintain the mobile responsiveness.
