Microsoft SharePoint Administration Toolkit
VIA SharePoint Team Blogs
The first tool, called "Batch Site Manager", adds new functionality through Central Administration. From the new "Move, Lock, and Delete Site Collections" page on Applications Management you can schedule bulk operations against site collections in the farm—including moving site collections between content databases.
The second tool is actually a new command in STSADM called "updatealert". This command will refresh all alert URLs in a specific site collection, which is extremely important should you change the URL of a web application or after an upgrade.
