Guidelines for content updates

These guidelines apply to all content updates. Refer to the topics for each update type for update-specific guidance.

Release information

Read any release notes or advisory text that accompanies a content update. This information describes compatibility, prerequisites, new capabilities, behavior changes, and warnings.

When to perform content updates

Follow these guidelines when performing and scheduling content updates:

  • Scheduled updates: Review scheduled updates to make sure they run at the right time for your environment.

  • Traffic inspection and flow: Perform updates that might interrupt traffic during maintenance windows.

Content updates are scheduled in Coordinated Universal Time (UTC), which remains constant year-round. Scheduled updates do not adjust automatically for local time changes, such as daylight saving time or summer time. For example, an update scheduled for 2:00 a.m. during standard time runs at 3:00 a.m. after the local clock moves forward.
