I have been using All-in-One SEO pack on one of my largest sites for about 4 years but have decided to change to WordPress SEO by Yoast for many reasons.
Any recommendations or Gotcha's that I should be aware of when making this switch? What happens to all of the settings on the 400+ posts currently posted under All-In-One SEO?
Will WordPress SEO by Yoast use the existing settings? Do I install Yoast and then de-activate All-in One?
