I'm happy to announce the release of the SharePoint Cross Site Collection Configurator! This functional sample source and solution deployment is designed to be simple to configure and easy to deploy, and is available now on Codeplex. Not only provides consistency and ease of deployment for IT and business standards, but it also supports much more flexibility in your information architecture so you can truly scale while having tens of thousands of site collections and not having to put all your eggs in one basket (single site collection with a single database). (Note super large scale tests have not been performed and it's recommended to test these in your environment.)
- Applying Master Pages across a SharePoint server farm.
- Applying audit settings across all my sites.
- Adding advanced settings such as “Allow content type management” to all types of lists.
- Adding a new Expiration Policy at the site collection level.
- Adding a new Expiration Policy to content types, lists, and documents.
