Before you migrate customizations from TestStand 2010 or earlier into TestStand 2012 or later, National Instruments recommends that you familiarize yourself with the process model plug-in architecture.

Note Note  Before you customize any process model files, National Instruments recommends that you copy the default <TestStand>\Components\Models directory to the corresponding <TestStand Public>\Components\Models directory and make modifications only to the files in the <TestStand Public> directory so you can easily revert unwanted changes by deleting the copy of the process model files in the <TestStand Public> directory.

The first step in successfully migrating existing customizations to TestStand 2012 or later is to determine where to implement changes in the newer process model files. Once you determine the new location for the customization, you must then consider how to integrate the changes with the changes present in the TestStand 2012 or later components.

In many cases, the TestStand components that contain the customizations you made also contain changes implemented in TestStand 2012 or later. This situation requires you to integrate the changes into a single file that contains the TestStand 2012 or later changes and the customizations you made. The approach you take for integrating files differs based on the following levels of complexity:

  • Changes you made to the component are less complex than changes implemented in TestStand 2012 or later—Determine the changes you made to the component and reapply the customizations to a copy of the TestStand 2012 or later version of the component.
  • Changes you made to the component are more complex than changes implemented in TestStand 2012 or later—Determine the changes between the TestStand 2012 or later version of the component and the original version of the component you modified and apply the TestStand 2012 or later improvements to the custom version of the component.

To facilitate this process, consider using one of the following recommended differ tools to quickly compare files.

File Type Recommended Differ Tool
Sequence file (.seq) TestStand File Diff and Merge utility
VI (.vi) LabVIEW Compare VIs dialog box
C code (.c, .h) Select Edit»Diff in LabWindows/CVI
Other files (non-binary) Third-party text differ
