Before diving into the migration, it’s essential to have a clear roadmap:

  • Identify Sources and Targets: Determine which databases or applications need migration.
  • Prioritize Factors: Consider downtime allowances, data volume, and application dependencies.
  • Engage with Oracle’s Planning Advisors: Oracle offers advisory services that can provide tailored migration strategies.

Preparation Steps

A successful migration starts with meticulous preparation:

  • Resource Provisioning: Ensure sufficient resources on Oracle Cloud@Customer for the incoming data.
  • Simulation: Use Oracle’s tools to simulate the migration process, identifying potential bottlenecks or issues.
  • Backup: Always have a backup of your source database to prevent data loss.

Executing the Migration

With preparations complete, it’s time to initiate the migration:

  • Data Transfer: Use Oracle’s Data Pump or GoldenGate to transfer data from the source to the target.
  • Ongoing Changes: If the source database remains active during migration, capture and apply these changes to the target database.
  • Validation: Ensure data integrity by validating data post-transfer.

Validation and Switchover

Post-migration steps are crucial to finalize the process:

  • Data Movement Confirmation: Ensure all data has been transferred without loss.
  • Performance Comparison: Compare database performance before and after migration.
  • Switchover Process: Once satisfied, switch operations to the new database on Oracle Cloud@Customer.

Choosing the Right Migration Method

Oracle offers multiple migration methods, each suited to different scenarios:

  • Oracle Data Pump: Best for offline migrations where some downtime is acceptable.
  • Oracle GoldenGate: Ideal for zero-downtime migrations, especially for large databases.
  • RMAN (Recovery Manager): Suitable for large databases requiring minimal downtime.
