copythe data folder from the XP's HD to the Win 10's HD into the appropriate folder (C:/.../8.4.5/).  I did the copy of
thedata folder, after renaming the new, unused data folder to preserve it).  I stopped the postgres service, made the
copy,and attempted to restart the postgres service.  No Go!  Would not start.  As a double-check, I renamed the copied
datafolder to something else and renamed the preserved data folder back to it's original name, and the service
restartedjust fine.

I’m guessing that the old machine was 32 but and the New is 64?  They have to match. You could always setup a 32 bit
VM.It must be 32 bit windows (if that’s what the original was )
