SharePoint 2013 does not support in-place upgrades of SharePoint 2010, meaning that SharePoint Server 2013 cannot be installed on a SharePoint 2010 server.
SharePoint 2007 must be upgraded to SharePoint 2010 before upgrading to SharePoint 2013. Likewise, K2 for SharePoint 2007 must be upgraded to K2 for SharePoint 2010 before upgrading to K2 for SharePoint 2013 in 2010 compatibility mode. For more information on individual components, please review K2 for SharePoint Component Compatibility: http://help.k2.com/kb001707
Follow Microsoft guidance for upgrading SharePoint environments. Note that only a Database Attach method of upgrading from SharePoint 2010 is supported by Microsoft. Follow the guidance in KB001210 when upgrading a K2 for SharePoint 2007 environment to K2 for SharePoint 2010.
Microsoft highly recommends that all SharePoint 2013 hosted sites use claims-based authentication, including those upgraded from SharePoint 2010. K2 will continue to work with claims-based authentication SharePoint sites as it does today.
Use this document as a guidance for moving to SharePoint 2013 in a K2 environment.

All site collections must maintain the same URL after the SharePoint upgrade for existing InfoPath-based artifacts to continue to work.
InfoPath forms must be configured for backwards compatibility (Advanced Form Options > Compatibility). Form types can be set to either “Web Browser Form (InfoPath 2010)” or “InfoPath 2010 Filler Form”.
