Cisco DNA Center's implementation of HA is described in the Cisco DNA Center High Availability Guide. We recommend that you first review this information and then determine whether you want to deploy HA in your production
environment. If you choose to do so, complete the following steps:
Click the Menu icon () in the Cisco DNA Center GUI and choose .
Click Activate High Availability.
After you click Activate High Availability, Cisco DNA Center enters into maintenance mode. In this mode, Cisco DNA Center is unavailable until the redistribution of services is completed. You should take this into account when scheduling an HA
Cisco DNA Center goes into maintenance mode every time you restore the database, perform a system upgrade (not a package upgrade), and activate
HA (as described above).
