Steve,
Yes, you definitely have to recompile your code.
The hardware architecture of a Vax is Complex Instruction Set Computers
(CISC); the architecture of an Alpha is Reduced Instruction Set Computers
(RISC); the compiled software on a Vax is unreadable on an Alpha.
We are going to do the same here. We are in the process of preparing the
live migration; testing was done last year.
Vax OpenVMS 7.3
PH 7.10G

Subject: Vax to Alpha - Recompile Needed?
G'day all
We have a client that is running a legacy PowerHouse system (7.10.g) on an
ageing Vax.
They want to move the application to an Alpha (currently on the same cluster
as the Vax) running the same version of Open VMS and the same version of
PowerHouse.
I've never moved a PowerHouse application to another box without upgrading
SOMETHING - so I've always recompiled. But in this instance the client is
insisting they do not want to recompile unless they really have to.
Can anyone tell me if there's a need to re-compile the code?
Regards,
Steve Heaslip
