Pre-Upgrade Information Check with AutoUpgrade
To obtain a checklist of tasks you must complete before upgrading an Oracle
Database on a physical server or virtual machine, run the AutoUpgrade utility
(autoupgrade.jar
) in analyze
mode.
Before starting your upgrade, ensure that you have a new release Oracle Database
installed and configured that you can use as the target for your upgrade. When your
target Oracle Database home is prepared, run AutoUpgrade with the
-preupgrade
clause on your system, using the instructions that you
can find in this guide.
Starting with Oracle Database 18c (18.5), and Oracle Database 12c Release 2 (12.2 and
the DBJAN2019RU or later Release Update), Oracle recommends run AutoUpgrade in
-analyze
mode for your target system before you upgrade Oracle
Database. AutoUpgrade can identify issues for you to address before you start your
upgrade. In certain cases, AutoUpgrade can also generate scripts that can resolve some
issues. Oracle recommends that you always download the most recent release of
AutoUpgrade.
