I quite a lot of experience doing this. It doesn't sound like you're running Adsense but I can honestly say that myself and other people have found a serious drop in earnings when moving to a new domain. It was an oversight on my part and there isn't anything definitive out there as a clear cut rule. I'm just suggesting that if you have some really nice click earnings those might be compromised for quite some time. I had a site of a few years and didn't think that those great clicks would go away but they certainly have in my situation. I'm looking at months since the move and have never heard a hard and fast rule about how long it might take to get back some of that click value.
