I am looking to upgrade my cluster from 6.7 to 7.0
I have ~200 indexes each with a doc type associated to it.
/index_name/document_name /index_name2/doctument_name2. ....
What happens to these document types after the upgrade? Are they accessible and just show a warning? Do they just go away? My concern is that I will do the update then somehow lock myself out of the indexes or blow something up. The data set is really large several TB, so when I make a mistake like that it takes a long time to clean up.
