Legacy L130, L230 units are end-of life and cannot be used with vSpace Pro. If your current version of "Classic" vSpace 6 works with your "aged" thin clients, it will not be affected, however, whenever you have the need to reinstall or re-register vSpace, this will no longer be possible and the only option will be to upgrade to current product.
The natural successor for the L series is the RX300
Regarding the X Series, NComputing stopped supporting the X Series on June 2016.
