Thanks for the response here, Jason. So, just to confirm, you're saying it is best to delete the original xyz.wpengine.com domain and add that as a redirect under our main domain name - in my case blog.smartbear.com (you may have come across it before).
Thanks again for keeping everything in context here.
Absolutely again. In both cases, people who had read this article commented saying they were glad to see it and re-read it. This is one of two posts that I would be fine re-posting year after year.
