Microsoft Web Deploy

Simplify the planning of your IIS 7.0 to IIS 8.0 migrations by determining incompatibilities and previewing the proposed changes before starting the process. Learning about any potential issues in advance gives you the chance to take corrective measures and simplifies migration.
Synchronize your server farm efficiently
The Web Deployment Tool allows you to efficiently synchronize sites, applications or servers across your IIS 8.0 server farm by detecting differences between the source and destination content and transferring only those changes which need synchronization. The tool simplifies the synchronization process by automatically determining the configuration, content, databases and certificates to be synchronized for a specific site. In addition to the default behavior, you still have the option to specify additional providers for the synchronization, including COM, GAC and registry settings.

Package, archive and deploy Web applications more easily

The Web Deployment Tool enables you to package configuration and content of your installed Web applications, including SQL databases, and use the packages for storage or redeployment. These packages can be deployed using IIS Manager without requiring administrative privileges. The tool also integrates with Visual Studio and WebMatrix to help developers streamline the deployment of Web applications to the Web server. System requirementsThe .NET 2.0 Framework SP1 or greater must be installed.
Internet Information Services 6.0 or 7.0 must be installed in order to perform operations on IIS.
