Microsoft SharePoint Administration Toolkit

Microsoft has released an Admin Toolkit for SharePoint which will allow you to move site collections between content databases. This will be useful to better manage the size of databases that have grown really large due to a specific site collection. The MSDN blog post can be found here: http://blogs.msdn.com/sharepoint/archive/2008/04/30/announcing-the-first-release-of-the-microsoft-sharepoint-administration-toolkit.aspx

Unfortunately they didn't add functionality to move a site to a different site collection or to another site...
