Close LV. Rename your old VI and name the new VI the same as the old one and have it in the same location. Start LV and load your VIs. The VIs will now find the new VI. If you want the new VI to have a different name from the old one open the VI and keep all the other loaded. Save the new VI with File >> Save As... under the new name. Be sure that the checkbox at the bottom of the dialog is not set. This way you will get the VI with the new name and all loaded VIs will reference to the new name. Then you can delete the new VI with the old name and rename the old VI to its original name.
