Migration from CEDR to DRS

I am trying to migrate Source Machine from CEDR to DRS. When trying to start the upgrade, getting below mentioned error:

# python3 cloudendure_to_drs_upgrade_tool.py start-upgrade --api-token <**APITOKEN**> --project-id <**ProjectID**> --aws-access-key-id <**ACCESSKEY**> --aws-secret-access-key <**SECRETKEY**> -–import-blueprint –-import-replication-configuration -–import-test-snapshot
Running the CloudEndure to DRS Upgrade tool.
usage: cloudendure_to_drs_upgrade_tool_internal_64 [-h]
                                                   {start-upgrade,finalize-upgrade}
                                                   ...
cloudendure_to_drs_upgrade_tool_internal_64: error: unrecognized arguments: -–import-blueprint –-import-replication-configuration -–import-test-snapshot

I have IAM user "DRSAgent" Created and have attached AWS Managed Policy "WSElasticDisasterRecoveryAgentInstallationPolicy" to it. Do I need to attach any other Policies? How can I overcome this error and proceed ahead with Migration?
