How do I update an automation that is on the old software?

Hi @VirginiaL31 , 

You can edit any email in the series by clicking the Actions dropdown to the right of the email in the series, and choosing Edit. From there, you can edit layout, font, colors, images, etc.

If you wanted to use a new template, the email would need to be recreated entirely. The text can be preserved by being copied & pasted, but the images would need to be re-inserted. At that point, I'd recommend creating a new automated series using our updated automation system, since you'd have to be recreating the emails entirely anyway.
