How do you do an intelligent redirect at the sub-site and site collection level?

Question

I need to migrate an entire site collection to another site collection. For various reasons, this process could take several days. We plan to migrate one sub-site at a time. While this process is going on, I would like to do an intelligent redirect.

For example: http://mycompany/sites/SC1/mypage.aspx?x=123 will redirect to http://mycompany/sites/SC2/mypage.aspx?x=123.

I know how to do this at the IIS level for a web application but haven't found a way to do it at the site collection or sub-site level.

This should be possible with very popular and widely used Add-on for IIS - the Url Rewriter. You can install it using Web Platform Installer. Here are some quick starts for you:

Looks like you may need to write as many rules as sub sites. A redirection rule can be added for a sub site when it is migrated.
