Moving Established Site to a another Domain

I had a similar situation to yours last may when I moved a PR 4 to a new domain. I was able to get the DMOZ entry and most other inbounds redone for the new site, however, the Y directory remains pointed to the old site. Aside from an update to the look and feel, content and page names remained the same as it was in the old site

G referers went down to almost 0 and remain there to this day. PR remains at 4, and G recognizes the Y backlink, even though it points to the old domain.

Yahoo seemed unfazed by the change, except it continued to use the old domain name and cacheing the new content. This resolved itself with Y's November fixes.

Too early to tell on MSN; of course this all happened before the new MSN went public.

If you are making this change for marketing purposes, you might consider redirecting the new domain to the old domain until Google sorts itself out, and then you can go ahead and use the new domain for marketing/email purposes.

Thanks, that was what I was worried about. I think I had better stick with the old domain, as the traffic is o.k. and the new domain isn't absolutely essential.
