I will be attempting to get the PC fixed for that. In the meantime, I removed the old PC HD, installing in a SATA to USB box and I installed the same version of Postgresql (8.4.5) on the Win 10 machine, thinking I could simply copy the 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 the data 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 data folder to something else and renamed the preserved data folder back to it's original name, and the service restarted just fine. > > So, without being able to backup or unload (dump?) the original database on the original PC, what would be the best way to move data to the new PC? Or, IS there any way to do this, without reviving the old XP, PC? 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 ) > > Dale >
