[jira] [Commented] (LUCENE-8004) IndexUpgraderTool should rewrite
segments rather than forceMerge
[ https://issues.apache.org/jira/browse/LUCENE-8004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16510104#comment-16510104 ]
Erick Erickson commented on LUCENE-8004:
----------------------------------------
Since LUCENE-7976 hasn't been added to 7.4, this is _not_ a blocker for 7.4.

> Spinoff from LUCENE-7976. We help users get themselves into a corner by using forceMerge on an index to rewrite all segments in the current Lucene format. We should rewrite each individual segment instead. This would also help with upgrading X-2->X-1, then X-1->X.
> Of course the preferred method is to re-index from scratch.
