You can use the Application Migration pages to manage the migration of applications from one system, or one version of a system to another.

Getting started with Application Migration

An outline of the steps you need to take after installing Application Migration to get you migrating applications through your OS Deployment Task Sequences.

Application Migration roles

Role-Based Access Control (RBAC) is a new feature in Tachyon platform 5.0 to enable administrators to control which Tachyon applications, tasks and data are accessible to specific users. This page outlines the roles associated with using and managing Application Migration and how they are configured.

Getting data into Application Migration

Application Migration pulls inventory data from Configuration Manager using the System Center Configuration Manager Connector in Tachyon. This page explains how to set up the Configuration Manager Connector, perform a data synchronization on-demand and schedule synchronization. 

Using the Installations page

The Installations page is the main Application Migration page where you can view which applications are installed in your environment, how frequently they're used, and if rules to migrate them have been defined. On this list you can also create and modify migration rules and exclude applications that you're not interested in.

Managing migration rules
Migration rules are used to define what happens to previously installed applications during an OS deployment. 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.
  • Adding a rule to retain an applicationA retain migration rule reinstalls exactly the same version of the application during the migration.
  • Adding a rule to replace an applicationA replace migration rule replaces an application with an alternative. This is useful for standardizing on common tools such as file compression applications.
  • Adding a rule to upgrade an applicationAn upgrade migration rule upgrades an existing application to a newer version.
  • Viewing and resolving migration rule conflicts

    Conflicts arising from having more than one migration rule for a computer belonging to more than one management group can be easily resolved before the migration takes place.

  • Working offline on migration rules

    You can export your installed applications to an Excel format file that can be worked on offline, with template columns that let you define new migration rules. Once you've finished defining the rules you can then import them back into Application Migration.

  • Managing Configuration Manager association alerts

    Application Migration users will see alerts on specific pages that 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.

Managing product exclusions

Products can be excluded from consideration by Application Migration, helping you to focus on the important products and minimizing effort during the Application Migration workflow.

Previewing post-OS migration application states

Before deploying the OS Deployment Task Sequence, you can preview the effect that Application Migration will have on the software installed on a device. This can be for existing or new build devices. This is done from Preview Device, where you can see the following menu items:

Menu itemDescription
Existing Device

Post-migration application status for existing computers undergoing an in-place upgrade or a computer refresh.

New Device

Applications to be installed on new-build computers by Management Groups or device attributes.

Role Based Application Sets

A Role Based Application Set defines a set of applications that should be installed on a computer for a user performing a particular role, or perhaps working at a particular location.

Setting the application installation sequence

In some cases, when some applications are installed together they need to be installed in a certain order. You can do this in Application Migration by adding the applications that have specific installation order constraints to the Application installation sequence.

Using Application Migration in a task sequence

The actual process of migrating applications is performed during an OS deployment task sequence in Configuration Manager.

Application Migration uses a custom task sequence step that calls an Application Migration API. The API gets a list of Configuration Manager Applications and Packages that need to be installed on a computer based on previously installed software titles (determined through inventory) and the migration rules applying to those titles.
