For a planned switchback, you must ensure that new contacts do not arrive into the DR Avaya Oceana® once the shutdown starts. You must close any Queued or In Progress contacts that an agent is processing. For example, to check if the status of all the current contacts for all channels is Processed and Closed, log in as an Avaya Oceana® supervisor and use Avaya Analytics™ real time displays. For more information, refer to the Avaya Oceana® and Avaya Analytics™ documentation suite.
