Hello,
After OpenSearch upgrade we note that these entries have been added to the persistent settings of the clusters:
{
"persistent" : {
"plugins" : {
"index_state_management" : {
"metadata_migration" : {
"status" : "1"
},
"template_migration" : {
"control" : "-1"
}
}
}
...
}
I haven’t found any documentation around them but I guess they were used to coordinate the migration. May I delete them now that clusters are happily upgraded? Is there any documentation around these that I missed? Many thanks in advance.
Have the same question, anybody has more information about this?

Hi,
I join the question
In a freshly deployed cluster, there is only one option:
GET _cluster/settings?flat_settings
...
{
"persistent": {
"plugins.index_state_management.template_migration.control": "-1"
},
"transient": {}
}
In the cluster log I constantly see the lines
[2023-03-07T06:31:48,899][INFO ][o.o.a.u.d.DestinationMigrationCoordinator] [node-data201] Detected cluster change event for destination migration
[2023-03-07T06:35:03,630][INFO ][o.o.a.u.d.DestinationMigrationCoordinator] [node-data201] Detected cluster change event for destination migration
[2023-03-07T06:35:04,182][INFO ][o.o.a.u.d.DestinationMigrationCoordinator] [node-data201] Detected cluster change event for destination migration
In existing clusters, two parameters as @spapadop wrote and the same lines in the log, although all nodes have long been updated and work
