Running Migration Tool version 1.6.12, downloaded today. Still the same bug that as been in all versions I have tried, namely in the generated command file the rsync commands have wrong source argument. On my SOURCE server the mail directories are in /home/vmail. I write this as answer to migtool question but still in the generated rsync commands the source argument is /var/vmail. My fix is to find an expression that matches only those problem rsync lines and do global replace to the correct text.
