Actually the colo machine is running Windows as well (not my call, but there are other workloads on it) but Ubuntu is running under VMWare, so I could install a truly identical copy of the colo "machine" on the same server I'm moving from... Thanks! Andy Shellam wrote: > Is there any chance of yo

Is there any chance of you setting up a temporary machine on the same network as your Windows one but an identical build as your co-located machine? Then you can transfer your Windows data to Linux using pg_dump/restore, switch your apps over to the Linux machine, then use WAL files to mimic t

From experience I would say NEVER NEVER try and do a direct copy across different platforms (Windows -> Linux.) Someone may contradict me, but I think a dump/restore would be the way to go. What sort of size of data are we talking? You'll need to factor in the time it takes to dump the data,

I'm in the process of moving a large database from an in-house Win32 server to a co-located Ubuntu Linux server. The data's in constant use, so I can't really bring the server down for more than a half hour or so, and I'd like to go ahead and use a base backup + WAL restore strategy to sync the ser
