OK so I installed WP 3.0 RC 3 and I got my main blog all upgraded. Then I enabled MULTI and set up the skeletons of 2 other blogs. One is an existing blog and the other one will be new so I can start from scratch with it. But about migrating the existing blog: The deal is it was in the same database but all its data has different previxes. The old version I was running was 2.8.4 So how can I get the data from the old blog into the new installation?
