Does Auctioneer create different data bases/info for each server you're on? I would think that it does, but when I went back to an older server of mine and was looking at things, it opened Auctioneer and seemed to be showing me prices from my other, main server where I'd been using Auctioneer.
data is all stored in the same file, however it is all separated from realm to realm, IE data from 'shattered hand' cannot be seen and used on 'zul'jin' so the data you are seeing on the old realm must have been collected from that realm. The only information that can cross over is profile settings
