• I wanted to migrate data from mongo db ec2 instance to document db – )

• Mongo db as a service is using ec2 instance –

• Same ec2 machine I have attached with document db.

• Mongo shell and db version ( 4.4.17 )

• I have already created end points source and target and tested successfully.

• DMS Replication instances has been created.

In Database migration tasks I am using task.
AWS DMS Status:
Load complete, replication ongoing.
However data is not getting replicated / migrated on target Document DB . After several minutes has been passed.

Can any one help?

• I have created replica set () in mongod conf. The failure error has been removed.
  The below issue didn’t resolve the issue.
• db.adminCommand({modifyChangeStreams: 1,
  database: “db_name”,
  collection: “”,
  enable: true});
