Catalyst Center's implementation of HA is described in the Cisco Catalyst Center High Availability Guide. Determine if HA is suitable for your production environment after reviewing the information. If you decide to continue, complete these steps for deployment:

1. From the main menu, choose System > Settings > System Configuration > High Availability.

2. Click Activate High Availability.

After you click Activate High Availability, Catalyst Center enters into maintenance mode. In this mode, Catalyst Center is unavailable until the redistribution of services completes. You must take this into account when scheduling an HA deployment.

Note

Catalyst Center goes into maintenance mode every time you restore the database, upgrade your system (not a package upgrade), and activate HA (as described).
