Hi Shawn,
Re-indexing is costly transaction in my use case as it takes more than three
days. Please let me know if any work around?
Thanks,

If you're upgrading more than one major version, you must reindex.
Multiple major version upgrades have always been discouraged and never
guaranteed to work, but now such upgrades are explicitly denied.
When you used the IndexUpgrader from Lucene 6, the Lucene version was written
into the index. The recorded version was preserved by the upgrader for version
7. When the index was subsequently read by version 8, it complained because
the original index was not written by version 7 or later.
Thanks,
Shawn
