Migrate migration docs from 6.0 to 7.0 (#26227) * Migrate migration docs from 6.0 to 7.0 Since we only keep one version of migration docs and master is now on 7.0, we should migrate these so breaking changes can be added in the right place. * Remove release notes as well They link to the migration guides, so they have to go. * Add placeholder notes for 7.0 so doc build is happy

[[breaking-changes-7.0]]
== Breaking changes in 7.0
This section discusses the changes that you need to be aware of when migrating
your application to Elasticsearch 7.0.
[float]
=== Indices created before 7.0
Elasticsearch 7.0 can read indices created in version 6.0 or above. An
Elasticsearch 7.0 node will not start in the presence of indices created in a
version of Elasticsearch before 6.0.
[IMPORTANT]
.Reindex indices from Elasticseach 5.x or before
=========================================
Indices created in Elasticsearch 5.x or before will need to be reindexed with
Elasticsearch 6.x in order to be readable by Elasticsearch 7.x. The easiest
way to reindex old indices is to use the `reindex` API.
=========================================
Disallow : in cluster and index/alias names (#26247) We use `:` for cross-cluster search (eg `cluster:index`), therefore, we should not allow the ambiguity when allowing cluster or index names. Relates to #23892
