Downtime is the period when the system is not available due to activities such as:

  • Patch upgrades

  • Database, hardware, or operating system maintenance

  • Configuration or customization changes

  • Migration.

You must plan your downtime and ensure that:

  • Downtime does not occur during critical and peak hours of system availability
