Select the characteristics of the source database, target service and requirements for the migration to identify available migration methods.

Key decision points include:

Migration Mode

• 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 the target database

Migration Type

• Logical migration

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

• Physical migration

• Captures source data and metadata using Recovery Manager and (optionally) ongoing changes with Oracle Data Guard
• Source and target databases must be the same version and platform types

Migration options are divided into Automated and Manual methods. Automated methods require configuration and are best suited for

• migration projects involving more than ten databases

• users who are not familiar with OCI operations such as wallet management and cloud registration since these are managed by the methods
