This tool, available for free from Microsoft, allows you to package entire web sites for migration to other servers as well as synchronising entire servers. It includes content, configuration and certificates.

Visit the Microsoft Web Deployment Tool web site for more documentation and download links

Have you tried the latest release, and will you please point to any community scripts that might have made the deployment process easier for syncing multiple targets?

No, I haven't had a need for it since writing this post.

The official site is here: http://www.iis.net/?tabid=20111so you may be able to find some resources there.
