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

Please don't post pictures of text, they are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them :slight_smile:
