Porting Applications from HP OpenVMS Alpha to HP OpenVMS Industry Standard 64

This document serves as a guide for developers porting applications from the OpenVMS Alpha operating system to OpenVMS Industry Standard 64 for Integrity Servers (OpenVMS I64). It outlines the porting process, fundamental architectural differences, and provides an evaluation checklist to help developers plan their migration effort. The guide covers compilation, linking, debugging, and testing considerations, as well as specific language-dependent requirements (such as for BLISS, Fortran, and C) and hardware-specific considerations for the Itanium processor family.
