Upgrade Measurement Data Services by backing up measurement data files, updating Measurement Data Services, and refreshing language packages.
- Shut down any application publishing data to MDS.
- Copy all files under My Documents\National Instruments\Measurement Data to a safe location.
-
Install the latest version of Measurement Data Services with Package Manager.
Refer to Package Manager for information about installing,
removing, and upgrading NI software.
Note Installing or upgrading Measurement Data Services does not update the TestStand result processor. If you already have TestStand installed and you install a newer version of MDS, only the data store service updates. The TestStand result processor remains at its existing version. To update the TestStand result processor, you must install the TestStand version that matches your version of MDS.
-
Update packages for your programming language.
Programming Language Installation Method LabVIEW Use Package Manager. Python Use pip install --upgrade ni.datastore or list ni.datastore as a dependency in your pyproject.toml file. C# In your project directory, run dotnet add package NI.DataStore.V1. Alternatively, you can list NI.DataStore.V1 in your .csproj file. - Launch MDS. This initial launch may take longer than usual due to database migration. Do not exit the application until the migration is complete.
- If necessary, add the files you backed up in step 2 back to My Documents\National Instruments\Measurement Data.
- Refer to Compatibility Considerations for a list of specific changes in each version of MDS that may break or alter application behavior.
