Here is the ERROR :-
java.lang.IllegalStateException: The index [[test-suites- tscount/kKudK8xxxxxxxxxxxXrvzAA]] was created with version [5.0.0] but the minimum compatible version is [6.0.0-beta1]. It should be re-indexed in Elasticsearch 6.x before upgrading to 7.6.2.

My Task is ....I want to upgrade my ES from 5.0.0 to 7.6.2 and i already upgrade to 6.8.13 version and now want to move to 7.6.2.

After i got update to 6.8.13 i got error above can read it.

Please help me How can i solve that issue without losing my ES DATA and update to v7.6.2
