The following table can help you decide on a migration strategy based on the source database characteristics.

Oracle Solution	Requirements
Oracle GoldenGate	Downtime must be kept to an absolute minimum. Source database and target database must be running on Oracle GoldenGate compatible platforms.
Oracle Data Guard	Source database can be Oracle Database 18c, Oracle Database 12c, or Oracle Database 11g Release 11.2.0.3, 11.2.0.4. Source database and target database must be running on Oracle Data Guard compatible platforms.
Oracle Recovery Manager (RMAN)	The database is a non- container database (CDB), which does not use the Oracle multitenant architecture. The database host platform uses little-endian byte ordering. Query `V$TRANSPORTABLE_PLATFORM` to view the byte ordering for different platforms.
Oracle Database Backup Cloud Service	Oracle Database 18c, Oracle Database 12c Release 12.2.0.1, 12.1.0.2, or Oracle Database 11g Release 11.2.0.4 with the latest PSU (patch set update) applied. If the database is at version 12.1.0.2 or later, it must be multitenant (CDB). Source database uses File System or Oracle Automatic Storage Management (Oracle ASM) as its storage method for data files.
