Domain Aliases when replacing content

Hi all,

I've posted a few times over the past week about the thin content penalties I have received. I am in the process of moving all of my content to new domains and my hosting provider suggested I try using a domain alias. I have never done this before and am curious if Google can detect this? In other words if they applied a manual action to Site A and Site B is an alias to Site A will the penalty transfer over? Site A is completely de-indexed in Google and all of the URLs have been switched over.

Anyway just curious if anyone has any feedback.

Thanks!

Why using alias? Just change the domain to the new one in 1. WP settings; 2. all links in database (assumed you use WP).

But anyway, the penalty can't follow. Unless they find the new site and review it.
