You can find the upgrade requirements in the release notes. For the Module itself the "what's new in this release" section always has that detail at the top.
IMC NTA 7.1 (E0301P03) can be upgraded from IMC NTA 7.1 (E0301), IMC NTA 7.1 (E0301H01), and IMC NTA 7.1 (E0301H02).
The platform requirements are spelled out in the "Installation Prerequisites" section:
IMC Platform Compatibility
o IMC Platform version: IMC PLAT 7.1 (E0303) or later
The excerpts aboce are from the NTAe0301P03 release notes, the NTAe0301 release notes list IMC plat e0301, but that's a minimum level so you should be good. The installer itself has a dependency check integrated, so it will complain and show an error if you try anything that isn't supported.
Thanks,
