[TYPO3-english] Please help: Moving from one template to another

[Joshua Heinrich Karp]

Hi,

I have constructed a site with a single template in TV. Due to some
cross-browser compatibility problems, I rewrote the HTML and CSS for this
template. The new HTML is completely different from the old markup, but the
field structure in the DS should basically remain the same. I would like to
create a new template in TV with this revised markup and then transfer the
site over to this new template.

I tried creating a new TV Data Structure, but when I switched a page over to
that template all the content from that page vanished -- I assume because
the file name and/or mapping had changed. That was disheartening.

Should I just replace the HTML file for my main template and remap the
fields?

I've scoured my Typo3 books, but I can't figure out how to proceed. What
should I do to create the new template, and then switch over without losing
all my content?

Best wishes,
Joshua
