This section discusses the changes that you need to be aware of when migrating
your application to {es} 8.0.
See also <<release-highlights>> and <<es-release-notes>>.
Remove `nGram` and `edgeNGram` token filter names (#38911) In #30209 we deprecated the camel case `nGram` filter name in favour of `ngram` and did the same for `edgeNGram` and `edge_ngram`. Using these names has been deprecated since 6.4 and is issuing deprecation warnings since then. I think we can remove these filters in 8.0. In a backport of this PR I would change what was a dreprecation warning from 6.4. to an error starting with new indices created in 7.0.

coming[8.0.0]
Move some token filter migration notes (#39072) The removal of the "nGram" and "edgeNGram" token filter was filed in a new migrate_8_0/mappings.asciidoc document but it should better be in an analysis.asciidoc section and file.

Unify blob store compress setting (#39346) Blob store compression was all implemented generally, except reading the setting for it. Moved the setting to BlobStoreRepository to unify this. Also removed deprecated env setting 'repositories.fs.compress'. This is a follow up on #39073

[float]
=== Indices created before 7.0
Elasticsearch 8.0 can read indices created in version 7.0 or above. An
Elasticsearch 8.0 node will not start in the presence of indices created in a
version of Elasticsearch before 7.0.
[IMPORTANT]
.Reindex indices from Elasticsearch 6.x or before
=========================================
Indices created in Elasticsearch 6.x or before will need to be reindexed with
Elasticsearch 7.x in order to be readable by Elasticsearch 8.x.
