MetaVis Change Manager extends Migrator functionality through the use of "Activities". Activities can be designed from any Migrator operations and can be mixed/matched and run against multiple SharePoint environments.
Unlike Migrator operations, activities can be scheduled to run at specific times and in a specific order. Activities also include additional auditing capabilities such as a pre and post-execution report for tracking and compliance.
Change Manager can be licensed to run along with the entire Architect Suite or Migrator products or as a standalone product.
