It helps them to achieve scalable and database-rich services for business growth. In this blog, we have covered different types of migration, tools, and key features of OCI Database Migration.

Different Types of Database Migration

You can migrate databases in different ways. Here are the 6 types of database migration.

Offline Migration

  • It generates a one-time copy of databases.
  • During the migration process, applications need to be offline.

Online Migration

  • At the time of migration, an initial copy of a database is followed by a change in data capture.
  • It enables applications to stay online during the migration.

It enables applications to stay online during the migration.

  • It creates blockwise copies of database files.
  • Database vendors and versions need to be the same on source and target.
  • There is no filtering or transformation.
  • It uses tools like RMAN and DataGuard.

Logical Migration

  • It works logically to interpret database contents and copy them to a database in the target format.
  • There will be different sources and targets.
  • The source and target may differ.
  • It uses tools like Data Pump and GoldenGate.

Direct Connection

  • It enables you to access source databases directly from the target network.
  • A VPN or FastConnect is needed for on-premise databases.

Indirect Connection

  • It does not allow the source database to be accessed directly from behind the Firewall.
  • It needs migration tools with agents.

OCI Database Migration: Key Features

Now, we will discover the capabilities of Oracle Database Migration.

  • Data is shared and dedicated on OCI during the migration from on-premises databases to Oracle Autonomous Data Warehouse (ADW) or Oracle Autonomous Transaction Processing (ATP).
  • It offers an OCI console for a self-service user experience.
  • It enables offline migration to move simple data with downtime.
  • The online migration method reduces downtime by using GoldenGate for the duplication of data.
  • During the migration phase, it can wait for user action and continue the task.
  • It enables you to move data through the OCI Object Store or Oracle Object Link.
  • When there is no direct connection between source and target databases, it disconnects offline migration with the help of agents behind the Firewall.
  • It allows for database migration from on-premises, third-party clouds, and within OCI to Autonomous Database.
  • It helps to prevent errors in database migration through job pre-checks for migration tasks using CPAT.
