OCI Database Migration

OCI Database Migration provides validated, cross-version, fault-tolerant, and incremental Oracle Database migrations for online and offline use cases. This free and easy-to-use service eliminates the need to learn Oracle’s portfolio of enterprise-class database migration tools.

How OCI Database Migration works

OCI Database Migration migrates Oracle Databases from on-premises or cloud deployments to OCI. The easy-to-use graphical user experience validates and manages migration workflows. Database Migration transparently uses Zero Downtime Migration, Cloud Premigration Advisor Tool, Data Pump, and GoldenGate services for secure, fault-tolerant, and incremental migrations.

OCI Database Migration (DMS) migrates Oracle databases from on-premises or cloud deployments to OCI. The easy-to-use graphical user experience validates and manages migration workflows. DMS transparently uses Oracle Zero Downtime Migration (ZDM), Cloud Premigration Advisor Tool (CPAT), Oracle Data Pump, and Oracle GoldenGate services for secure, fault-tolerant, and incremental migrations.

OCI Database Migration (DMS) migrates Oracle databases from on-premises or cloud deployments to OCI. The easy-to-use graphical user experience validates and manages migration workflows. DMS transparently uses Oracle Zero Downtime Migration (ZDM), Cloud Premigration Advisor Tool (CPAT), Oracle Data Pump, and Oracle GoldenGate services for secure, fault-tolerant, and incremental migrations. Supported source databases can be on-premises, OCI, or in other cloud providers. Using the OCI Database migration service, users register source and target databases and select between online or offline migration. In the validation phase, Cloud Premigration Advisor assesses source and target compatibility, looks for potentially problematic content, and makes recommendations. After all errors are resolved, data is first loaded through Data Pump, and the user has a choice between loading the target through intermediate storage in Object Store or a direct database link between the source and target database. In the online case, after the initial load, ongoing replication uses GoldenGate.

OCI Database Migration supports the following database sources and targets. The flexibility of a logical migration allows version upgrades and changes to target platforms.

sources and targets OCI Database Migration supports the following Oracle source database versions: 11g, 12c, 18c, and 19c, Standard and Enterprise editions. These deployments can be on-premises, on OCI or OCI Classic, or on Amazon RDS. The configurations include standard database instances, Oracle RAC One Node, and Oracle RAC. Target platforms can be Autonomous Databases, both ATP and ADW shared and dedicated, and they can be comanaged databases, such as Base Database Service on VM, bare metal, or Exadata Cloud Service.

Migration workflows meet both simple and complex operational requirements without the need for advanced DBA skills. Migrations can run whether applications are online, offline, or across firewalls. For long running migrations, source and target data is always available without impacting source database performance. If migration involves modernization, workflows also enable version upgrades and hardware platform changes.

Migration workflows meet both simple and complex operational requirements without the need for advanced DBA skills. You can conduct a database migration either offline or online with the following target OCI Database offerings: Base Database Service, Exadata Database Service, or Autonomous Database. Database Migration service supports logical migration. If your source is not reachable through a direct connection, then the service supports indirect connection via the use of an agent.

Migration workflows


Offline migration

  • Applications are offline during migration
  • Duplicates entire database in one operation

Online migration

  • Applications are online during migration
  • Captures incremental source database changes in real-time and continuously applies them to target database

Data movement


Logical migration

  • Captures source data and metadata separately from physical data using Data Pump and GoldenGate
  • Enables source and target databases to be different versions and platforms

Network connection


Direct connection

  • Source and target are on the same physical or virtual network

Indirect connection

  • Source and target are on separate networks and likely behind firewalls
  • Access across networks requires a secure agent

Embedded migration advisor

A comprehensive diagnostic advisor is embedded into the migration workflow. The advisor prioritizes exceptions, suggests resolutions, and generates repair scripts. Users can interactively review the details and either ignore the warnings, exclude source objects, or make repairs. The convenience of this essential step streamlines the migration workflow.

migration advisor The migration advisor process has five steps. 1: Identify the source and target versions. 2: Identify exceptions in the form of "Action Required," "Review Required," and "Review Suggested." 3: Present findings, including exception detail and repair advice, and provide repair scripts. 4: Users take actions on the findings, including accept, run repair scripts, reject, or exclude. 5: After actions are taken, rerun the advisor. Additional buttons allow you read or watch a demonstration of this process.

“Our customers expect production database migrations to be risk free with minimal downtime. With the OCI Data Migration Service, all the setup, administration, validation, and workflow needed is automated. You only need to provide connectivity between the source and the target databases because DMS manages everything transparently.”
