Hi, We recently upgraded our clusters from 4.1.5 to 5.0.3 and now I’m trying to migrate SSTable files to the new oa-* format, but it’s not working as I expected.
What I Tried: nodetool flush + upgradesstables → Completed quickly with success messages, but no SSTables were rewritten. nodetool upgradesstables -a → Triggered compactions, but new SSTables are still in the old nb-* format. What’s the recommended approach to ensure SSTables migrate to oa-*? Is it really necessary? Thanks! Luciano
