AFAIK that's kind of hard. If you have access to a newer LabVIEW version and you bought the toolkit, you could maybe save it backwards. If you don't have access to a newer LabVIEW version you could be out of luck potentially.
I don't know if there would be any issue legally or technical in using community or a newer "freely" available LabVIEW version, to revert your purchased toolkit to a previous version.
If you know other programming languages/have experience with other toolkits you could also implement your own bindings to use other toolkits from within LabVIEW. But that's probably more time consuming.
