[jira] [Commented] (KAFKA-15381) Controller waiting for migration should only allow failover when transactions are supported

    [ https://issues.apache.org/jira/browse/KAFKA-15381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17800587#comment-17800587 ] 

Stanislav Kozlovski commented on KAFKA-15381:
---------------------------------------------

Changing target fix version to 3.8 since this is not a blocker and we are cutting a 3.7 RC

> After a KRaft controller starts up in migration mode, it enters the "pre-migration" state. Unless transactions are supported, it is not safe for the controller to fail over in pre-migration mode. This is because a migration could have been partially committed when the failover occurs.
