Application Migration intelligently automates the migration of applications during a Configuration Manager OS deployment. Using migration rules (defined by an administrator), previously installed applications can be reinstalled, upgraded or replaced with an alternative during an OS deployment task sequence.

These rules can include usage criteria, allowing you to choose to only install previously installed applications if they were being used, or perhaps replace a rarely used application with a less costly alternative. This functionality enables applications to be actively rationalized during an OS migration exercise, standardizing on products and versions and reclaiming unused software.

Application Migration is implemented as a Tachyon application and a custom Configuration Manager task sequence step. The Tachyon platform provides inventory data from Configuration Manager, normalized through the 1E Catalog, that it uses to determine the applications installed and used on each computer.

The 1E Application Migration task sequence step is added to an existing OS Deployment Task Sequence. This step calls the Application Migration API on the Tachyon Server to return a list of Configuration Manager Applications and Packages that need to be installed, based on the source computer's inventory and applicable Application Migration rules. The Applications and Packages are installed using the standard Configuration Manager Install Application and Install Package steps, each configured to install based on dynamic variables defined in the 1E Application Migration step. For details, please refer to Using Application Migration in a task sequence.

New features in Application Migration 3.0:

  • New user interface - The Application Migration user interface has been integrated into the common 1E platform user interface to provide a common look and feel across 1E products.
  • Manage association of Configuration Manager applications and packages independently of migration rules - Configuration Manager associations are now managed in the Tachyon Inventory application, separate from migration rules which are still managed in the Application Migration application - please refer to Tachyon 5.0 - Manage associations for more details. This enables administrators to associate their Configuration Manager applications and packages with products from the 1E Catalog, before creating migration rules. It also makes it easier to identify applications installed in the environment that do not have an associated application or package in Configuration Manager to install them. Administrators can still continue to add or change associations from the Manage Rules and Role Based Application Sets pages.
  • Identify orphaned Configuration Manager applications or packages - Previously, it was not easy for an administrator to identify migration rules or role-based application sets that referenced applications or packages that had been deleted from Configuration Manager. Administrators now see alerts on the Manage Rules and Role Based Application Sets pages which identify orphaned applications when one or more rules or applications in an application set reference Configuration Manager objects that no longer exist, or where the Configuration Manager association has been deleted. For more information please refer to Managing Configuration Manager association alerts.
  • Install applications in a particular sequence - Administrators can now define the order in which certain applications should be installed. This feature supports scenarios where some combinations of applications must be installed in a particular sequence if they are to co-exist on the same device. For more information please refer to Setting the application installation sequence.
  • Export device migration preview data - Administrators can export the data from the Device Preview page to an Excel spreadsheet, which can be shared with end users prior to the migration of their device.
