Source RDS instance ID or source PolarDB cluster ID. This parameter is mandatory only when CreationOption is set to MigrationFromRDS, CloneFromRDS, CloneFromPolarDB, or RecoverFromRecyclebin.

• If CreationOption is MigrationFromRDS or CloneFromRDS, you need to input the source RDS instance ID. The source RDS instance version must be RDS MySQL 5.6, 5.7, or 8.0 High Availability edition.

• If CreationOption is CloneFromPolarDB, you need to input the source PolarDB cluster ID. The DBType of the cloned cluster will default to match the source cluster. For example, if the source cluster is MySQL 8.0, the cloned cluster must also have DBType set to MySQL and DBVersion to 8.0.

• If CreationOption is RecoverFromRecyclebin, you need to input the released source PolarDB cluster ID. The DBType of the cluster being recovered from the recycle bin must match the source cluster. For example, if the source cluster was MySQL 8.0, the recovered cluster must also have DBType set to MySQL and DBVersion to 8.0.
