Volt MX Go is a tool that allows developers to extend existing Domino applications with next-generation user experiences. It provides features like the Domino adapter, design import, VoltFormula, and First Touch setup to easily connect Volt MX apps to Domino backends. This allows developers to maximize their investment in existing Domino apps and skills while adding new mobile and web capabilities. The roadmap includes additional features like VoltScript to execute existing Domino code in Volt MX and enhancements to import more design elements with less coding. HCL recommends using Volt MX Go along with advisory and implementation services to modernize targeted Domino applications.
