This chapter provides information and instructions to take DC1 out of production and into a shutdown or standby mode to perform a switchover to DC2.

Avaya Oceana® supports the following options for full and partial switchover operations during planned maintenance windows:

• Planned full switchover of all Disaster Recovery (DR) components of the solution - All components with a DR capability undergo a switchover.

• Planned partial switchover of Avaya Oceana® (Avaya Breeze® platform nodes and Omnichannel Database) - Customers do not have to switchover any of the following surrounding applications deployed with DR capabilities in an Avaya Oceana® and Avaya Analytics™ DR solution provided they are fully operational.

  • Avaya Aura® Communication Manager with ESS.

  • Avaya Control Manager with any of its supported HA or DR deployments.

  • Avaya Aura® Session Manager with a Geo-Redundant System Manager deployment.

Planned full or partial switchover

You can perform a planned full or partial switchover even when there are no failures in any part of the solution. You can perform this activity in the following scenarios:

• To test the DR configuration and capabilities in the event of unexpected partial or full failures. Preventive testing enables failover and maintenance timeframes to be recorded based on individual customer configurations.

• Partial switchovers may be required to perform software and patch upgrades. Testing the DR capabilities of the Avaya Oceana® and Avaya Analytics™ components, supports the planning of scheduled maintenance times required to perform these activities.

Advantages of performing a planned switchover

Planned maintenance windows are defined as customer-agreed time periods where the deployed solution is taken out of production and put into a shutdown or standby mode to perform a switchover and a switchback between the two parts of the DR solution.

There are several advantages of performing a planned switchover of Avaya Oceana® and Avaya Analytics™ DR solution:

• Existing contacts can be processed in a controlled manner.

• New contacts cannot enter into the system queue after the switchover procedures start.

• Logged-in agents can access the currently queued contacts.

• Active contacts can be cleared before the shutdown or failover in both primary and failover scenarios.

• Supervisor users logged in using Avaya Workspaces can view real-time reports and displays to ensure a graceful shutdown of all existing contacts.
