Erick Erickson commented on LUCENE-8004:
----------------------------------------

Since LUCENE-7976 hasn't been added to 7.4, this is _not_ a blocker for 7.4.

> IndexUpgraderTool should rewrite segments rather than forceMerge

> 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.
