Preparing the target database for migration

Before you can migrate data with Oracle Cloud Infrastructure Database Migration, manually configure your target database as described here.

To configure an Autonomous database as a target for migration, run the following SQL commands:
```
-- Global Names
ALTER SYSTEM SET GLOBAL_NAMES=FALSE;
```
To configure a non-Autonomous, single-tenant (non-CDB) or a specific pluggable database (PDB) within a multi-tenant (CDB) as a target for migration, run the following SQL commands:
```
-- Global Names
ALTER SYSTEM SET GLOBAL_NAMES=FALSE;
```
To configure a non-Autonomous, multi-tenant (CDB) as a target for migration, run the following SQL commands:
```
-- Connect to CDB and run:
-- Global Names
ALTER SYSTEM SET GLOBAL_NAMES=FALSE;
```
