Looks like you have an issue with passwords, retrieved from your source. You have an error:
Your password is not complex enough. According to the server policy, the minimal password strength is Strong. To improve the password strength, use numbers, upper and lower-case characters, and special characters like !,@,#,$,%,^,&,*,?,_,~
Actually, Plesk Migrator should temporary decrease password strength in target Plesk at the period of migration, but looks like in you case it does not happen. We will try to found a root cause and fix it, but now you can simply decrease password strength in target Plesk manually, perform migration and then set it back to "Strong".
Debug log could contain sensitive data, so it is not good idea to post it in public thread. Could you please remove attached file from you previous post?
