Failover to the Disaster Recovery Site

If the servers at site 1 are no longer viable, activate site 2. Once site 2 is activated, the FTL configuration can be managed at site 2. The messaging functions of site 1 are been available at site 2.

  1. Use the REST API to activate the FTL configuration at site 2 (command "activate_dr"). Optionally remove "drfor" from the site 2 YAML files.

  2. Clients and satellites need to reconnect to site 2. Remap the DNS or restart them.

  3. Update the realm configuration to activate messaging at site 2. This requires two changes to the persistence cluster: disable disaster recovery replication, and make site 2's server set the active server set. (Disaster recovery replication can be re-enabled later for a planned failback.)
