> The segment format changes introduced for tail compaction (OAK-3349) must not require an explicit migration step. Instead there should be a rolling migration during normal operation. 
> Things to consider:
> * Segments from Oak 1.6
> * Changes in tar index formats induced by the segment format changes
> * Changes in gc.log induced by the segment format changes
> * Required changes in the repository manifest and its interpretation
