The pre-upgrade checklist is a set of recommended tasks to complete before beginning an upgrade to ensure system integrity and reduce downtime.
-
Back up the application directory, such as /opt/cgms , before upgrading specific components like cgms RPM .
-
Back up the database to preserve data before the upgrade process.
Before starting the upgrade, perform the following tasks to ensure a smooth and successful upgrade process:
-
Back up the application directory. For example, if you want to upgrade cgms RPM , then you must back up the /opt/cgms folder. For more information, refer to Installing or Upgrading the SSM Server .
-
Back up the database. For more information, refer to Creating a Full Backup of the IoT FND Database , Backing Up the IoT FND Database Incrementally .
After the upgrade, the manual changes made to the application scripts are lost.
For instance, before upgrading the cgms RPM, back up the /opt/cgms directory and ensure a full database backup is completed to prevent data loss.
