XML not loading everything

Hey guys!

I’m working with a blognetwork, and did ran in to the same issue again and again.

Some blogs with alot of data doesn’t seam to upload everydata by XML upload – I have to upload the file multiple times, and even after 50 uploads its not perfect.

We’re moving bloggers from WP to WP and also from WP to WPMU, and from WP > WPMU I can’t just do a mySQL download>upload.
