Configure OS image relationships

Mar 28, 2016
  1. From the AppDNA side bar, choose Import & Analyze > Operating Systems.
  2. In the list of OS images in the Operating Systems screen, select the OS image that you want to configure.
  3. On the toolbar, click OS Image Relationships.
  4. On the left side, under Are you moving, select one of the following options:

    To this operating system image – Select this option if the new OS image represents an OS (such as Windows 8.1) to which you are preparing to migrate. The right side of the screen then lists the available legacy OS images.

    From this operating system image – Select this option if the new OS image represents an OS that you are migrating from. The right side of the screen then lists the available target OS images.

  5. On the right side of the screen, select the OS image(s) that you want AppDNA to compare with the OS image you are configuring. Deselect any OS images that are not relevant.

    For best results, select only those images that are relevant to the analysis that you want to perform.

  6. Click Save on the toolbar to preserve your changes.

    Depending on the changes you have made to the configurations, you may now need to analyze your applications in order for the changes to be reflected in reports. If this is necessary, the Analyze button on the far right side of the toolbar is enabled. If necessary, click Analyze to analyze the applications. Alternatively, you can analyze the applications later in the normal way.

Example

Suppose you are migrating from Windows XP to Windows 8.1 and want to import desktop and laptop images for both Windows XP and Windows 8.1.

  • When you import and configure the Windows XP laptop image, select From this operating system image and then select the Windows 8.1 laptop image as the target image.
  • When you configure the Windows 8.1 laptop image, select To this operating system image and then select the Windows XP laptop image as the legacy image.

After that, perform the equivalent steps for the desktop images. When you run the analysis for the Windows 8.1 report, AppDNA compares the changes between the Windows XP and Windows 8.1 laptop images and between the Windows XP and Windows 8.1 desktop images. To view the reports, choose whether to view the report for the laptop images or the desktop images.

This example describes setting up OS image relationships in which there is a one-to-one relationship between the images. However, this is not a requirement. For example, you could import one legacy OS image and four target OS images and configure all four of the target OS images with the single legacy OS image.
