ADOM Design

Enable ADOMs to support devices other than FortiGates, upgrades of FortiGates not supported by ADOM migration, and upgrading policy package versions. See When to enable ADOMs.

When upgrading FortiGate versions, if possible, use the same ADOM. See Upgrading the firmware of managed devices.

Upgrade in the following order:

  1. FortiGate.
  2. ADOM.
  3. Global (if used).

Before upgrading the FortiGate, confirm that the current FortiManager version is compatible with the new FortiGate version. If not, upgrade the FortiManager first.

ADOM revisions (see ADOM revisions):

  • Use for significant changes.
  • Implement a deletion policy to limit the number of retained revisions.

Periodically clean up unused objects. See What to do with unused objects.

For more information, see the FortiManager Administration Guide.

ADOM considerations

A large number of ADOMs can significantly increase the size of configuration files which increases backup and restore time. Do not create more ADOMs than your business needs.
