AWS Datamigration Service
- At a high level there are 3 systems in this architecute
- source db
- destination db
- replication db
- replication db will be in AWS, where source and destination db can be anywhere but they need to have connection from replication
- In most of the migrations
- Source db => On-prem
- Destination db => rds
- Our lab scenario is to migrate data from on-premise mysql to aws rds
- Refer Here for different migrations documented
- Lets navigate to database migration service
- Create a target endpoint by creating a free tier rds mysql instance
- Create a replication instance in DMS
- Now test the source endpoint created
- Now lets create an rds endpoint (target)
- Now create a Database migration task
- Now restart/resume the migration task
- Note : In include rules try to give the schema name of the database to be migrated
- For migrating databses offline, we can use Refer Here
- mysql dump
- s3 bucket
