Hello,
Currently, there is no cross reference document available to perform a comparision between these two versions of Spread, as Spread v1.0.8 is quite an old version of Spread. You can refer to the following documentaion link of Spread.Net 7v2:
http://helpcentral.componentone.com/NetHelp/SpreadNet7/WF/webframe.html
I would request you to elaborate the specific issues and your exact requirement, so that we can accordingly guide you ahead with the same.
Thanks,
Manpreet Kaur
