This why I like LVM's, I'd have just moved the LVM over to the new server and voila, there you go.
Other than that, if you have the normal installation that OpenACS recommends (installing everything in one directory), then you can copy over the whole directory (this is what we ususally do). No problems so far. Same is true if you use multiple mount points aso. It does not hold true though if you use RAW devices. In this case you can only use the copy trick if you have LVM.
