@satyapackirisamy,

If you can access to the back-end of our migration tool, you can run this command to solve the issue you mentioned.

rm -rf /opt/lampp/htdocs/magento2/app/code/Ubertheme/Ubdatamigration/lib/

However, our script here uses an outdated codebase, thus we no longer maintain and replace with a newer Pro version here.

We highly recommend you consider our Pro version, it definitely saves you pretty much time.

Regards,
Ubertheme team

Thank you for your valuable Reply.

Glad we can help.
As mentioned above, the current script you're using might have unexpected issues due to the outdated codebase. Anyway, you can proceed a testing migration if you choose to.
