Pluggable Database (PDB) Migration & Upgrade from 12c to 19c using Full Transportable Tablespace Export-Import
There are many ways to migrate PDB like Remote Clone, Unplug – Plug, RMAN. Here we will explore Full transportable tablespace export/import method that is fast and efficient. We will be migrating a pluggable database (TESTHIST) running on Oracle 12C in Windows OS to Oracle 19C in Oracle Linux which both of them have Little Endian….so there will be no conversion process taking in place.
With Full Transportable Tablespace Export/Import combines the benefit of both Transportable Tablespace & Export/Import. You need to transfer only the user datafiles to the target host and use Expdp/Impdp to take metadata information backup like Table definition, Grants, Procedure, Triggers, etc, and import them into the target database and will upgrade your PDB directly to the source version.

Below are the high-level steps we will follow to perform Migration & Upgrade
1. Validate Source PDB
2. Validate Target CDB
3. Check User tablespaces are self-contained
4. Create metadata dump
5. Copy the dump file and the data file to the destination database server
6. Create empty PDB in Target CDB
7. Add PDB TNS Entry and create datapump directory
8. Import medadata
9. Verify new PDB
Below are setup details and the same will be used in this demonstration.
| Sr. No. | OS | Hostname | IP | CDB@PDB | DB Version |
| 1 | Window | test-machine01 | 192.168.114.177 | CDB1@TESTHIST | 12.1.0.2.0 |
| 2 | Oracle Linux | test-machine02 | 192.168.114.176 | CDB2@TESTHIST | 19.3.0.0.0 |
Step 1. Check Source PDB: Query view: V$TRANSPORTABLE_PLATFORM to identify the endian format of your operating system. Here we will migrate PDB: TESTHIST which has user tablespace: TEST_DATA and application user: APP_USER.

Step 2. Check Target CDB: Query view: V$TRANSPORTABLE_PLATFORM to identify the endian format of your operating system. Since both source and target operating system is Little Endiness no conversion is required. We can directly attach the datafiles to our target PDB.

Step 3. Check User tablespaces are self-contained: The following check will ensure from the physical and logical side that there are no dependency user objects stored under SYSTEM, SYSAUX tablespaces. As we need to transfer only User tablespaces to the target host. Execute the below procedure and check for any violation. if no violation set the source tablespaces in “READ_ONLY” mode.

Step 4. Create metadata dump: Take the metadata backup using the below expdp command. Please note we are using tnsname: testhist to connect to our source PDB: TESTHIST. Since it’s only metadata backup and not actual user data backup, that is very fast and also at the end of expdp command, it will mention datafiles need to transfer to the destination or target host.

Step 9. Verify new PDB: Please note we had 51 error(s) in import operation the reason for this is if you compare number of components in DBA_REGISTRY in source and target PDB. Target PDB has fewer components than Source PDB, so it’s a good idea to install missing components in Target PDB before we start import.
