This is an unknown actually. However I made this post because I believe they'll be abandoning the alpha SPARC site after conversion. For instance. https://sparc.network now forwards to https://kingsds.network

Compare the archive.org of sparc.network: https://web.archive.org/web/20180331043724/https://sparc.network/ to https://kingsds.network

The SPARC that's on the website is currently within their smart contract and isn't "yours" until you claim it, it isn't clear what will happen to it, so to be on the safe side, withdraw it to an ETH wallet so it gets converted to their new token.
