FortiSIEM HA — Migration from Environment 1 to Environment 2 and Promotion of the New Environment

Hello everyone. I am finalizing a FortiSIEM HA migration and am facing significant difficulties in completing the process stably. The goal is to completely decommission Environment 1—currently acting as the primary environment—and promote Environment 2 to take over as the new primary FortiSIEM environment. During the process, I encountered inconsistencies involving Patroni, etcd, PostgreSQL, and node synchronization. Even after reconfiguration, references and records from the previous environment can persist in the cluster, hindering the establishment of Environment 2 as the new Leader and the formation of a stable HA setup. I would like to know if anyone has performed this type of transition and could share their experience—specifically regarding the permanent removal of Environment 1, the promotion of Environment 2 as the new primary environment, the cleanup of old references in Patroni and etcd, HA reconfiguration, and validation steps to preserve the CMDB, database, events, and services. If anyone has encountered this scenario and can share the procedure used, best practices, or key considerations, I would greatly appreciate it.

HELP!!!

I don't know what to do anymore.
