Our project was just converted.
One of our trackers was not migrated. It was our spam hiding tracker so it's loss is not important and I have created a new one.
The original tracker id's appear to have been lost. Are these available in some undocumented field or as a cross reference.
Most of the new UI mouse hover help text is empty. This is making learning the new system harder than it should be. With Firefox the mouse over status bar url is somewhat useful, but with IE the status bar space is to small to get the hint.
