One of the more likely reasons why it fails to migrate is because of the
package's dependencies.  For example, it may depend on a particular
version of a library and until that version is also available.  We may
have a cascade of dependencies, and so until all the dependencies are
fully available then the uploaded package won't go into the release
pocket until the the dependencies are available.

I'd look at
http://people.canonical.com/~ubuntu-archive/proposed-migration/update_output.txt
to double check for errors such as this.
