I am currently running 1.7.1 and would like to upgrade to 2.1  
When I am trying to use the Migration Plugin v0.16, I get a warning that I may loose data  
[http://localhost:9200/\_plugin/migration/test\_index\_segments.html](http://localhost:9200/_plugin/migration/test_index_segments.html)  
warning is: "TEST INDEX SEGMENTS - THIS TEST SUITE IS DESTRUCTIVE"

[http://localhost:9200/\_plugin/migration/test.html](http://localhost:9200/_plugin/migration/test.html)  
warning is: "CAUTION: THIS TEST SUITE WILL DELETE ALL YOUR DATA"

Don't run those, just run the checks under [http://localhost:9200/\_plugin/migration](http://localhost:9200/_plugin/migration).
