Convert flash template?

I have old flash templates.
Is there a way to convert them, or would you prefer to start all over?

If I have to start all over with the template, is there anywhere a guide on how to still use the flash templates a bit longer?

There is a topic about that here.

There is no easy way to convert Flash templates to HTML. I usually use the Flash templates for a show until a redesign is done and then create new HTML templates using After Effects and Blueprint.
