Once your business is live with an Oracle Utilities Cloud Service, hot fixes will be available for the most recent Maintenance Pack.

After that you must take up the subsequent General Availability release on average every four months, with the exact timing of each release determined by you within our Production Lane guidelines. Skipping one or more releases is not allowed. You can take the next General Availability release into one or more non-production environments first for testing, which should focus on any customized areas of your system. At this point the General Availability release will already be out of the Fast Lane, so the fixes are limited to critical/blocking issues faced by you or other customers getting ready for production use. If upgrade testing on the next General Availability release needs to continue for an extended period you can choose a 'freeze level' for stabilization, then will need to take a mandatory 'catch up' to the last maintenance pack of the release (at the sixth month after General Availability). This is similar to the initial go-live and gives you the ability to test the release as needed and stay current in your production environment.
