Audit log is retained after node deletion, same for syslog.
For event log there's Events.DeleteEventsOfDeletedObject setting in Configuration->Server Configuration, if set to true (default), they are deleted. And there's similar setting for alarms - Alarms.DeleteAlarmsOfDeletedObject.
DCI data is deleted.
If database is Postgres Timescale, then event log and DCI history is not deleted.
In all above situations when data is not deleted, it would be problematic to view it since you need to know node's ID.
New decommissioning functionality is basically node unmanage with addition of automatic deletion at later time. So for now you can just unmanage your nodes.
