Switching themes..any issues?

Hey, I currently have the SOLON theme but am thinking of changing to Hiero. I don’t want to lose any of the work I have done to the current SOLON theme so by changing it over to a new one will I have to redo everything? “Re-do everything” as in re-write the articles, re-write the pages, color, text box’s and content?

You won’t lose your content, but the colors are different and you’ll lose them.
