Hello @amitabh.jain,

Thank you for contacting us about this. It appears the issue is caused by this line:

caused by: liquibase.exception.LockException: Could not acquire change log lock. Currently locked by f1ab74d41290 (172.17.0.2) since 8/12/19 7:06 PM

You can release the lock manually by executing the SQL query below on the Confluence database. 

If that doesn't work, please Raise a Support Ticket with our Migration Team and include a copy of your Support Zip, and we'll be able to help you out.

Best regards,

Shannon
