The Question is: We currently have 2 Alpha machines, both running VMS 7.1. One system is an Alpha 200 4/166, the other is an Alpha 200 4/233. Is it possible to load an Image from the Alpha 166 system to the Alpha 233? If so, is there anything 'out of the ordinary that needs to be done to accomplish this'? Any assistance would be greatly appreciated. Best regards Cory Brace The Answer is : This transfer should work just fine. OpenVMS is explicitly designed and explicitly intended to permit user-mode applications to be cross-compatible across platforms of the same version, ECO level and architecture, and also to permit user-mode applications to be upward-compatible across OpenVMS versions and ECOs. No rebuilds, no recompilations, and no code changes are expected to be required. Applications that operate in privileged processor modes (eg: executive or kernel mode code, device drivers, etc) may be platform-specific or may require a rebuild or rework when OpenVMS is upgraded. (Specifically on OpenVMS VAX V6.0 and later, user-mode and privileged-mode code should upgrade without changes.) Applications containing latent bugs or that are dependent on platform- specific features or on undocumented features may, of course, have some problems with upgrades or with different patforms. (For one specific example of a latent error, please see the details and information in the 21264 directory of the OpenVMS Freeware V4.0 distribution.)
