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 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:
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|
Customizations typically fall into one of following categories:
