Delphix supports migrating from a vPDB in a virtual CDB, to another linked or virtual CDB. This feature is only available through the command-line interface.

Note

Attempts to perform this migration via GUI will fail with the following error:

Error
The operation could not be completed because the virtual database “vPDB1" is disabled.
Error Code
exception.db.genericvdb.disabled

This topic describes how to migrate a virtual pluggable database (vPDB) in a virtual CDB to another virtual CDB using the command-line interface.

Pre-requisites

You should already set up and have Delphix discover a container database in the same environment as the vPDB currently is or from an environment to which the vPDB will be migrated to.

Procedure

Log into the Delphix command-line interface using the admin user or a user with admin privileges.
```
ssh admin@YOUR_ENGINE
```

Disable the vPDB.

delphix> /source
delphix source> select myPDB
delphix source 'myPDB'> disable
delphix source 'myPDB' disable *> commit
    Dispatched job JOB-35
    SOURCE_DISABLE job started for "myPDB".
    Disabling virtual database "myPDB".
    Unexporting storage containers.
    Virtual database "myPDB" disabled.
    SOURCE_DISABLE job for "myPDB" completed successfully.
delphix source 'myPDB'>

Change the environment user and repository ( ORACLE_HOME ) for the vPDB to the appropriate user from the new host.

delphix> /sourceconfig
delphix sourceconfig> select myPDB
delphix sourceconfig 'myPDB'> update
delphix sourceconfig 'myPDB' update *> set repository='/u01/app/oracle/product/19.0.0.0/dbhome_1'
delphix sourceconfig 'myPDB' update *> set environmentUser='/oracle'
delphix sourceconfig 'myPDB' update *> commit
    Dispatched job JOB-38
    SOURCE_CONFIG_UPDATE job started for "myPDB".
    SOURCE_CONFIG_UPDATE job for "myPDB" completed successfully.

Change the environment user and repository ( ORACLE_HOME ) for the vCDB to the appropriate user from the new host. This must match the settings in step 3.

delphix sourceconfig 'myPDB'> /sourceconfig/
delphix sourceconfig> select myCDB
delphix sourceconfig 'myCDB'> update
delphix sourceconfig 'myCDB' update *> set repository='/u01/app/oracle/product/19.0.0.0/dbhome_1'
delphix sourceconfig 'myCDB' update *> set environmentUser='/oracle'
delphix sourceconfig 'myCDB' update *> commit
    Dispatched job JOB-39
    SOURCE_CONFIG_UPDATE job started for "myCDB".
    SOURCE_CONFIG_UPDATE job for "myCDB" completed successfully.

Enable the vPDB.

delphix sourceconfig 'myCDB'> /source
delphix source> select myPDB
delphix source 'myPDB'> enable
delphix source 'myPDB' enable *> commit
    Dispatched job JOB-40
    SOURCE_ENABLE job started for "myPDB".
