Hi, I upgrade the cluster from 7.16.1 to 8.19.1 as per the upgrade guide. The kibana ugprade assistant did’t report anything. Now I’m upgrading to version 9.2.3 where getting the below issue for security index.

The index .security-7 created in version \[7.16.1\] with current compatibility version \[7.16.1\] must be marked as read-only using the setting \[index.blocks.write\] set to \[true\] before upgrading to 9.2.3

Any correct procedure to migrate this .security-7 index to new one? Setting it to true didn't help.

Thanks
