一、前提：
1.源库和目标库运行的主机版本一致。
Red Hat Enterprise Linux Server release 7.8 (Maipo)
2.数据库版本保持一致。（19C）
SQL> select banner from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production
3.数据库文件目录需要保持一致。
Notes:如果数据文件必须被拷贝至不同目录，例如ASM盘；只需要在create pluggable database时设置参数 SOURCE_FILE_NAME_CONVERT
官方文档对source_file_name_convert的说明：
Specify this clause only if the contents of the XML file do not accurately describe the locations of the source files.
If the files that must be used to plug in the source database are no longer in the location specified in the XML file,
then use this clause to map the specified file names to the actual file names.二、迁移步骤：
1、Non-CDB open to read_only model in the source database
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area 629144664 bytes
Fixed Size 8899672 bytes
Variable Size 184549376 bytes
Database Buffers 432013312 bytes
Redo Buffers 3682304 bytes
Database mounted.
SQL> alter database open read only;
Database altered.
2、Non-CDB Create the XML file for the PDB in the source database
SQL> exec DBMS_PDB.DESCRIBE('/home/oracle/orclpdb.xml');
PL/SQL procedure successfully completed.

3、Shutdown the Non-CDB database in the source database
SQL> select instance_name,status from v$instance;
INSTANCE_NAME STATUS
---------------- ------------
orcl OPEN
SQL> select open_mode from v$database;
OPEN_MODE
--------------------
READ ONLY
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
4、Change directory to the new Oracle home，Run the DBMS_PDB.CHECK_PLUG_COMPATIBILITY function in the target database
--If the output is YES, then the PDB is compatible
set serveroutput on
DECLARE
compatible CONSTANT VARCHAR2(3) :=
CASE DBMS_PDB.CHECK_PLUG_COMPATIBILITY(
pdb_descr_file => '/home/oracle/orclpdb.xml',
pdb_name => 'ORCLPDB')
WHEN TRUE THEN 'YES'
ELSE 'NO'
END;
BEGIN
DBMS_OUTPUT.PUT_LINE(compatible);
END;
12 /
YES
PL/SQL procedure successfully completed.
5、Plug Non-CDB database to PDB in the target database
SQL> create pluggable database orclpdb using '/home/oracle/orclpdb.xml' nocopy tempfile reuse;
Pluggable database created.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB01 MOUNTED
4 ORCLPDB MOUNTED
5 PDB02 MOUNTED
6 PDB03 MOUNTED
6、Run the noncdb_to_pdb.sql script in the target database
SQL> alter session set container=ORCLPDB;
Session altered.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
4 ORCLPDB MOUNTED
SQL> @?/rdbms/admin/noncdb_to_pdb.sql
--由于内容过多，已省略
7、open orclpdb in the target database
SQL> show con_name
CON_NAME
------------------------------
CDB$ROOT
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB01 MOUNTED
4 ORCLPDB MOUNTED
5 PDB02 MOUNTED
6 PDB03 MOUNTED
SQL> alter pluggable database ORCLPDB open;
Pluggable database altered.
SQL> alter session set container=ORCLPDB;
Session altered.
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
4 ORCLPDB READ WRITE NO
