Online Migration

Previously, for order migration, first, the existing orders need to be migrated through the migration service. Then all the new requests can be processed by Orchestrator once the orders are migrated. So there is a possible downtime during the transition of the orders.

Now the process has been changed and there is no downtime for the migration. The requests can be processed even for the orders those are being migrated. The orders are fetched from the migrated version and if it does not find the orders, then fetches the orders from the older version.

To enable this online migration service, set the migrationEnabled flag value as true in the $OM_HOME/roles/configurator/standalone/config/ConfigValues_OrchService.xml file.
