I spent 7 hours waiting for this tool to migrate a 14GB site to WPE. I kept stalling out and never got past 5% and was stuck in the tables portion of the migration. I cancelled it and downloaded the legacy migration tool and it's screaming along. Took only a few minutes to do the tables and now just a few minutes later it's over 10% done on the files. I may have to find some other tool or service when the legacy one stops working. Sad.
