Oracle Database Autoupgrade Utility is a new feature designed in Oracle 19c to automate the Upgrade process which Identifies issues before upgrade, Performs Preupgrade actions, Deploying the upgrades and Performs Post upgrade actions . You can upgrade multiple databases at the same time using a single configuration file.

Description
In this article I will demonstrate an overview on upgrading Oracle database from 12.2.0.1 to 19.3.0.0 using Oracle Database Autoupgrade utility.
Below are the High level steps:
- Install Oracle 19.3.0.0 binaries
- Prerequisite for Autoupgrade
- Create the config file
- Analyze the database
- Deploy the upgrade
- Post upgrade task
Environment Details:
Source Hostname: new19c
Database version: 12.2.0.1
Database Name: cdbdev
ORACLE_HOME: /u01/app/oracle/product/12.2.0/db_1/
Target Hostname: new19c
Databaes Version: 19.3.0.0
Database name: cdbdev
ORACLE_HOME: /u01/app/oracle/product/19.3.0/dbhome_1Source DB Details
SQL> select name, open_mode, version, status from v$database, v$instance;

--------- -------------------- ----------------- ------------
CDBDEV READ WRITE 12.2.0.1.0 OPEN1. Install Oracle 19.3.0.0 binaries
I have already completed the installation of 19c, Refer here for step by step installation of Oracle 19.3.0.0 on Linux 7 64bit.
2. Prerequisite for Autoupgrade
Download the latest autoupgrade.jar file
Autoupgrade utility autoupgrade.jar file exists by default under $ORACLE_HOME/rdbms/admin directory from Oracle 19.3 release onwards, however Oracle strongly recommends to download the latest AutoUpgrade version before doing the upgrade. Click here to download the latest version.
Replace the autoupgrade.jar with the latest version downloaded
[oracle@new19c ~]$ mv $ORACLE_HOME/rdbms/admin/autoupgrade.jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar-bkp
[oracle@new19c ~]$ cp /tmp/autoupgrade.jar $ORACLE_HOME/rdbms/admin/
[oracle@new19c ~]$
[oracle@new19c ~]$ $ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -version build.hash e84c9c2
build.version 19.10.0
build.date 2020/10/23 10:36:46
build.max_target_version 19
build.supported_target_versions 12.2,18,19
build.type productionJava version
Java version should be 8 or later, which is available by default in Oracle Database homes from release 12.1.0.2 and latest.
[oracle@new19c temp]$ $ORACLE_HOME/jdk/bin/java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
[oracle@new19c temp]$3. Create the config file
Create a directory to hold all upgrade config and log files.
[oracle@new19c ~]$ mkdir /u01/19c-autoupg
[oracle@new19c ~]$ cd /u01/19c-autoupgCreate the sample config file
cd /u01/19c-autoupg
export ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1
export PATH=$PATH:$ORACLE_HOME/jdk/bin
$ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -create_sample_file config
--output
[oracle@new19c ~]$ cd /u01/19c-autoupg
[oracle@new19c 19c-autoupg]$ export ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1
[oracle@new19c 19c-autoupg]$ export PATH=$PATH:$ORACLE_HOME/jdk/bin
[oracle@new19c 19c-autoupg]$ $ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -create_sample_file config
Created sample configuration file /u01/19c-autoupg/sample_config.cfgModify the config file
Copy the sample config file and make the necessary changes as per the database environment.
cd /u01/19c-autoupg
cp sample_config.cfg cdbdev_db_config.cfg
vi cdbdev_db_config.cfgThis is the config file I used for upgrade:
[oracle@new19c 19c-autoupg]$ cat cdbdev_db_config.cfg
global.autoupg_log_dir=/u01/19c-autoupg/upg_logs
#
# Database cdbdev
#
upg1.dbname=cdbdev
upg1.start_time=NOW
upg1.source_home=/u01/app/oracle/product/12.2.0/db_1/
upg1.target_home=/u01/app/oracle/product/19.3.0/dbhome_1
upg1.sid=cdbdev
upg1.log_dir=/u01/19c-autoupg/upg_logs/cdbdev
upg1.upgrade_node=new19c
upg1.target_version=19.3
upg1.run_utlrp=yes
upg1.timezone_upg=yes4. Analyze the database
Autoupgrade Analyze mode checks your database to see if it is ready for the upgrade. This will reads data from the database and does not perform any updates.
Execute autoupgrade in analyze mode with the below syntax,
export ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1
export PATH=$PATH:$ORACLE_HOME/jdk/bin
cd /u01/19c-autoupg
$ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -config cdbdev_db_config.cfg -mode ANALYZEOutput
[oracle@new19c 19c-autoupg]$ $ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -config cdbdev_db_config.cfg -mode ANALYZE

5. Deploy the upgrade
Autoupgrade Deploy mode performs the actual upgrade of the database from preugrade source database analysis to post-upgrade checks.
Note: Before deploying the upgrade, you must have a backup plan in place.
Execute the autoupgrade in DEPLOY mode using the below syntax,
export ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1export PATH=$PATH:$ORACLE_HOME/jdk/bincd /u01/19c-autoupg$ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -config cdbdev_db_config.cfg -mode DEPLOYOnce the upgrade process is started consider monitoring the logs to see the progress of the upgrade. Autoupgrade logs are available under,
/u01/19c-autoupg/upg_logs/cdbdev/cdbdev/101/dbupgradeOutput
[oracle@new19c 19c-autoupg]$ $ORACLE_HOME/jdk/bin/java -jar $ORACLE_HOME/rdbms/admin/autoupgrade.jar -config cdbdev_db_config.cfg -mode DEPLOY
