Location of MSI file – Specify the OS image MSI that you want to import. The OS image MSI must be located in the same folder as the three XML files that are also generated by Snapshot Manager:
Create new image – Select this option to create a new OS image within AppDNA (the default). Then enter the name and description:
Overwrite existing image – Select this option to overwrite an existing OS image within AppDNA, and then select the OS image that you want to overwrite. This option is available only for OS images that you have imported. You cannot overwrite the system OS images (the OS images that come with AppDNA).
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.
For best results, select only those images that are relevant to the analysis that you want to perform.
When you import the first image in a pair, you cannot select the other one because it has not been imported yet. You can therefore leave this section blank and configure the image later in the Operating Systems screen.
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.
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.
When the import is complete, AppDNA shows the results and which reports require re-analyzing in order for the new OS image to be reflected in reports.
