Saving for a Previous Version

You can save VIs for a previous version of LabVIEW to make upgrading LabVIEW convenient and to help you maintain the VIs in two versions of LabVIEW when necessary. If you upgrade to a new version of LabVIEW, you can go back to the last version of the VIs.

Complete the following steps to save a hierarchy of VIs for a previous version of LabVIEW.

  1. For the top-level VI in your hierarchy of VIs, select File»Save with Options to display the Save with Options dialog box.
  2. Select Save for Previous to save the VI hierarchy for the previous version.
    Note  When you save a VI hierarchy that uses a LabVIEW toolkit that has provided LabVIEW with a list of version information, you can select which version of the toolkit to save your VI hierarchy for in the Toolkit Version field.
  3. Click the Save button to display the Choose a Directory dialog box.
  4. Select the directory where you want to save the VI hierarchy.
  5. Click the Save button.

If a VI uses functionality that is not available in the previous version, LabVIEW saves as much as it can and produces a report of what it could not convert. The report appears immediately in the Save for Previous Warnings dialog box. Click the Save button to save the warnings to a text file you can review later or click the OK button to acknowledge these warnings and close the dialog box.

You also can use the Save For Previous method to save a VI for a previous version of LabVIEW programmatically.
