Zephyr migration tool not migrating data

Hi, 

We are using Zephyr migration tool for migrating zephyr data from Jira server to Jira cloud. I followed all steps provided in documentation. Log says Migraiton completed. But If I see in Jira cloud for the respective projects we migrated no data is migrated , only test cycle folder is created and no tests are added to it and no steps or execution nothing seems to be migrated. Kindly advise on how to take it forward. 

Thanks,

Baskar
