Due to the ongoing nature of software improvement, vendors will issue patches and service packs for the operating systems, application servers and database servers on top of specific versions that Oracle Utilities Customer Care and Billing has been tested with.

If it is necessary to apply an upgrade, please do so in a test environment that is running on the same platform as your production environment prior to updating the Oracle Utilities Customer Care and Billing production environment.

Note that Oracle 19c is an exception from this rule. Do not upgrade it.

Always contact Oracle Utilities Customer Care and Billing Support prior to applying vendor updates that do not guarantee backward compatibility.
