I am having an issue with the repository migration assistant. It gets as far as the 'Select Data to Migrate' page and then shows an error in the log file and no v7 elements are available in the window to drag to the v9 side.
The error is:
Timestamp: 07 December 2011 09:20:41

Obviously something not quite right in the mapping. perhaps a duplicate value somewhere but no indication of where it might be or what to trace.
If anyone can point me in the right direction it would be most appreciated.
Thanks,
Karl.
