- Introduction: Since Oracle 12c, the CDB (Container Database) and PDB (Pluggable Database) model has been the recommended architecture. Oracle has announced that non-CDB architecture is deprecated (and not supported starting from Oracle 21c). So migrating is necessary if you are upgrading to a newer Oracle version.
- Patch consideration: If the instances are not at the same patch level, you will get PDB violations visible in the PDB_PLUG_IN_VIOLATIONS view.
- If the destination is at a higher patch level than the source, then run the datapatch -verbose utility on the destination instance in the normal way. It may throw any error and also suggest what action needs to be taken.
- If the destination is at a lower patch level than the source, you will need to run a datapatch -rollback operation.
- Methods of migration:
- DBMS_PDB Package (Plugging method)
- Creating the PDB via DB Link
- Export/Import Method
- Prerequisites:
- On the target, there one must be a multitenant (CDB) database, if not then create the same.
- Environment:
DBMS_PDB Package (Plugging method)
| Server | Non-CDB | CDB |
|---|---|---|
| Hostname | MISN | REPORT |
| IP | 192.168.80.51 | 192.168.80.52 |
| OS | OEL 9 | OEL 9 |
| SID | MISN | REPORT |
| Patch Level | 19.24 | 19.27 |
| PDB | NA | MISD |
As per above details we have Non-CDB & CDB Databases on different servers. So we will create Non-CDB instance on target and then do the restoration with the backup of Source Non-CDB dataabase. We will use RMAN utility for the same.
1. Take precheck & RMAN backup at source:
First create a table with test user so that data can be validated post migration:
SQL> show user
USER is "TEST1"
SQL>
SQL> def
DEFINE _DATE = "27-APR-25" (CHAR)
DEFINE _CONNECT_IDENTIFIER = "misn" (CHAR)
DEFINE _USER = "TEST1" (CHAR)
DEFINE _PRIVILEGE = "" (CHAR)
DEFINE _SQLPLUS_RELEASE = "1924000000" (CHAR)
DEFINE _EDITOR = "vi" (CHAR)
DEFINE _O_VERSION = "Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production

DEFINE _O_RELEASE = "1924000000" (CHAR)

7. Now plug the Non-CDB database MISN into CDB REPORT database. We have below options for maintaing the database files:
- COPY - With this option, all data files of Non-CDB will remain untouched. For PDB files will be copied to the new location, provided with the parameter FILE_NAME_CONVERT.
- NOCOPY - Existing files will be used and after completion of the operation, Non-CDB will not remain usable. As new PDB is using the same data files.
- MOVE - using parameter FILE_NAME_CONVERT, existing datafiles will be moved to the new location, hence after the operation completion, Non-CDB will not be usable.
==> Create Directory for datafiles & tempfiles.
