When attempting to connect to and load a list through the Navigator in Migration Suite for Sharepoint, the following error is being thrown:
"Error loading data: Server returned HTTP response code: 500 for URL: https://sourcesitename/_vti_bin/lists.asmx"
List Throttling in Central Admin is causing the tool to timeout.
WORKAROUND:
Under Profile Manager | Global Variables, enable 'Slow Query Method.'
